Ivy Grant, SVP of Strategy & Operations, Twilio June 13, 20255 Min Readpeshkova via alamy stockAsk technologists and enterprise leaders what they hope AI will deliver, and most will land on some iteration of the "T" word: transformation. No surprise, AI and its “cooler than you” cousin, generative AI (GenAI), have been hyped nonstop for the past 24 months. But therein lies the problem. Many organizations are rushing to implement AI without a grasp on the return on investment (ROI), leading to high spend and low impact. Without anchoring AI to clear friction points and acceleration opportunities, companies invite fatigue, anxiety and competitive risk. Two-thirds of C-suite execs say GenAI has created tension and division within their organizations; nearly half say it’s “tearing their company apart.” Most (71%) report adoption challenges; more than a third call it a massive disappointment. While AI's potential is irrefutable, companies need to reject the narrative of AI as a standalone strategy or transformational savior. Its true power is as a catalyst to amplify what already works and surface what could. Here are three principles to make that happen. 1. Start with friction, not function Many enterprises struggle with where to start when integrating AI. My advice: Start where the pain is greatest. Identify the processes that create the most friction and work backward from there. AI is a tool, not a solution. By mapping real pain points to AI use cases, you can hone investments to the ripest fruit rather than simply where it hangs at the lowest. Related:For example, one of our top sources of customer pain was troubleshooting undeliverable messages, which forced users to sift through error code documentation. To solve this, an AI assistant was introduced to detect anomalies, explain causes in natural language, and guide customers toward resolution. We achieved a 97% real-time resolution rate through a blend of conversational AI and live support. Most companies have long-standing friction points that support teams routinely explain. Or that you’ve developed organizational calluses over; problems considered “just the cost of doing business.” GenAI allows leaders to revisit these areas and reimagine what’s possible. 2. The need for (dual) speed We hear stories of leaders pushing an “all or nothing” version of AI transformation: Use AI to cut functional headcount or die. Rather than leading with a “stick” through wholesale transformation mandates or threats to budgets, we must recognize AI implementation as a fundamental culture change. Just as you wouldn't expect to transform your company culture overnight by edict, it's unreasonable to expect something different from your AI transformation. Related:Some leaders have a tendency to move faster than the innovation ability or comfort level of their people. Most functional leads aren’t obstinate in their slow adoption of AI tools, their long-held beliefs to run a process or to assess risks. We hired these leaders for their decades of experience in “what good looks like” and deep expertise in incremental improvements; then we expect them to suddenly define a futuristic vision that challenges their own beliefs. As executive leaders, we must give grace, space and plenty of “carrots” -- incentives, training, and support resources -- to help them reimagine complex workflows with AI. And, we must recognize that AI has the ability to make progress in ways that may not immediately create cost efficiencies, such as for operational improvements that require data cleansing, deep analytics, forecasting, dynamic pricing, and signal sensing. These aren’t the sexy parts of AI, but they’re the types of issues that require superhuman intelligence and complex problem-solving that AI was made for. 3. A flywheel of acceleration The other transformation that AI should support is creating faster and broader “test and learn” cycles. AI implementation is not a linear process with start here and end there. Organizations that want to leverage AI as a competitive advantage should establish use cases where AI can break down company silos and act as a catalyst to identify the next opportunity. That identifies the next as a flywheel of acceleration. This flywheel builds on accumulated learnings, making small successes into larger wins while avoiding costly AI disasters from rushed implementation. Related:For example, at Twilio we are building a customer intelligence platform that analyzes thousands of conversations to identify patterns and drive insights. If we see multiple customers mention a competitor's pricing, it could signal a take-out campaign. What once took weeks to recognize and escalate can now be done in near real-time and used for highly coordinated activations across marketing, product, sales, and other teams. With every AI acceleration win, we uncover more places to improve hand-offs, activation speed, and business decision-making. That flywheel of innovation is how true AI transformation begins to drive impactful business outcomes. Ideas to Fuel Your AI Strategy Organizations can accelerate their AI implementations through these simple shifts in approach: Revisit your long-standing friction points, both customer-facing and internal, across your organization -- particularly explore the ones you thought were “the cost of doing business” Don’t just look for where AI can reduce manual processes, but find the highly complex problems and start experimenting Support your functional experts with AI-driven training, resources, tools, and incentives to help them challenge their long-held beliefs about what works for the future Treat AI implementation as a cultural change that requires time, experimentation, learning, and carrots (not just sticks) Recognize that transformation starts with a flywheel of acceleration, where each new experiment can lead to the next big discovery The most impactful AI implementations don’t rush transformation; they strategically accelerate core capabilities and unlock new ones to drive measurable change. About the AuthorIvy GrantSVP of Strategy & Operations, Twilio Ivy Grant is Senior Vice President of Strategy & Operations at Twilio where she leads strategic planning, enterprise analytics, M&A Integration and is responsible for driving transformational initiatives that enable Twilio to continuously improve its operations.

Extra-sensory perception The nine-armed octopus and the oddities of the cephalopod nervous system A mix of autonomous and top-down control manage the octopus's limbs. Kenna Hughes-Castleberry – Jun 7, 2025 8:00 am | 19 Credit: Nikos Stavrinidis / 500px Credit: Nikos Stavrinidis / 500px Story text Size Small Standard Large Width * Standard Wide Links Standard Orange * Subscribers only   Learn more With their quick-change camouflage and high level of intelligence, it’s not surprising that the public and scientific experts alike are fascinated by octopuses. Their abilities to recognize faces, solve puzzles, and learn behaviors from other octopuses make these animals a captivating study. To perform these processes and others, like crawling or exploring, octopuses rely on their complex nervous system, one that has become a focus for neuroscientists. With about 500 million neurons—around the same number as dogs—octopuses’ nervous systems are the most complex of any invertebrate. But, unlike vertebrate organisms, the octopus’s nervous system is also decentralized, with around 350 million neurons, or 66 percent of it, located in its eight arms. “This means each arm is capable of independently processing sensory input, initiating movement, and even executing complex behaviors—without direct instructions from the brain,” explains Galit Pelled, a professor of Mechanical Engineering, Radiology, and Neuroscience at Michigan State University who studies octopus neuroscience. “In essence, the arms have their own ‘mini-brains.’” A decentralized nervous system is one factor that helps octopuses adapt to changes, such as injury or predation, as seen in the case of an Octopus vulgaris, or common octopus, that was observed with nine arms by researchers at the ECOBAR lab at the Institute of Marine Research in Spain between 2021 and 2022. By studying outliers like this cephalopod, researchers can gain insight into how the animal’s detailed scaffolding of nerves changes and regrows over time, uncovering more about how octopuses have evolved over millennia in our oceans. Brains, brains, and more brains Because each arm of an octopus contains its own bundle of neurons, the limbs can operate semi-independently from the central brain, enabling faster responses since signals don’t always need to travel back and forth between the brain and the arms. In fact, Pelled and her team recently discovered that “neural signals recorded in the octopus arm can predict movement type within 100 milliseconds of stimulation, without central brain involvement.” She notes that “that level of localized autonomy is unprecedented in vertebrate systems.” Though each limb moves on its own, the movements of the octopus’s body are smooth and conducted with a coordinated elegance that allows the animal to exhibit some of the broadest range of behaviors, adapting on the fly to changes in its surroundings. “That means the octopus can react quickly to its environment, especially when exploring, hunting, or defending itself,” Pelled says. “For example, one arm can grab food while another is feeling around a rock, without needing permission from the brain. This setup also makes the octopus more resilient. If one arm is injured, the others still work just fine. And because so much decision-making happens at the arms, the central brain is freed up to focus on the bigger picture—like navigating or learning new tasks.” As if each limb weren’t already buzzing with neural activity, things get even more intricate when researchers zoom in further—to the nerves within each individual sucker, a ring of muscular tissue, which octopuses use to sense and taste their surroundings. “There is a sucker ganglion, or nerve center, located in the stalk of every sucker. For some species of octopuses, that’s over a thousand ganglia,” says Cassady Olson, a graduate student at the University of Chicago who works with Cliff Ragsdale, a leading expert in octopus neuroscience. Given that each sucker has its own nerve centers—connected by a long axial nerve cord running down the limb—and each arm has hundreds of suckers, things get complicated very quickly, as researchers have historically struggled to study this peripheral nervous system, as it’s called, within the octopus’s body. “The large size of the brain makes it both really exciting to study and really challenging,” says Z. Yan Wang, an assistant professor of biology and psychology at the University of Washington. “Many of the tools available for neuroscience have to be adjusted or customized specifically for octopuses and other cephalopods because of their unique body plans.” While each limb acts independently, signals are transmitted back to the octopus’s central nervous system. The octopus’ brain sits between its eyes at the front of its mantle, or head, couched between its two optic lobes, large bean-shaped neural organs that help octopuses see the world around them. These optic lobes are just two of the over 30 lobes experts study within the animal’s centralized brain, as each lobe helps the octopus process its environment. This elaborate neural architecture is critical given the octopus’s dual role in the ecosystem as both predator and prey. Without natural defenses like a hard shell, octopuses have evolved a highly adaptable nervous system that allows them to rapidly process information and adjust as needed, helping their chances of survival. Some similarities remain While the octopus’s decentralized nervous system makes it a unique evolutionary example, it does have some structures similar to or analogous to the human nervous system. “The octopus has a central brain mass located between its eyes, and an axial nerve cord running down each arm (similar to a spinal cord),” says Wang. “The octopus has many sensory systems that we are familiar with, such as vision, touch (somatosensation), chemosensation, and gravity sensing.” Neuroscientists have homed in on these similarities to understand how these structures may have evolved across the different branches in the tree of life. As the most recent common ancestor for humans and octopuses lived around 750 million years ago, experts believe that many similarities, from similar camera-like eyes to maps of neural activities, evolved separately in a process known as convergent evolution. While these similarities shed light on evolution's independent paths, they also offer valuable insights for fields like soft robotics and regenerative medicine. Occasionally, unique individuals—like an octopus with an unexpected number of limbs—can provide even deeper clues into how this remarkable nervous system functions and adapts. Nine arms, no problem In 2021, researchers from the Institute of Marine Research in Spain used an underwater camera to follow a male Octopus vulgaris, or common octopus. On its left side, three arms were intact, while the others were reduced to uneven, stumpy lengths, sharply bitten off at varying points. Although the researchers didn’t witness the injury itself, they observed that the front right arm—known as R1—was regenerating unusually, splitting into two separate limbs and giving the octopus a total of nine arms. “In this individual, we believe this condition was a result of abnormal regeneration [a genetic mutation] after an encounter with a predator,” explains Sam Soule, one of the researchers and the first author on the corresponding paper recently published in Animals. The researchers named the octopus Salvador due to its bifurcated arm coiling up on itself like the two upturned ends of Salvador Dali’s moustache. For two years, the team studied the cephalopod’s behavior and found that it used its bifurcated arm less when doing “riskier” movements such as exploring or grabbing food, which would force the animal to stretch its arm out and expose it to further injury. “One of the conclusions of our research is that the octopus likely retains a long-term memory of the original injury, as it tends to use the bifurcated arms for less risky tasks compared to the others,” elaborates Jorge Hernández Urcera, a lead author of the study. “This idea of lasting memory brought to mind Dalí’s famous painting The Persistence of Memory, which ultimately became the title of the paper we published on monitoring this particular octopus.” While the octopus acted more protective of its extra limb, its nervous system had adapted to using the extra appendage, as the octopus was observed, after some time recovering from its injuries, using its ninth arm for probing its environment. “That nine-armed octopus is a perfect example of just how adaptable these animals are,” Pelled adds. “Most animals would struggle with an unusual body part, but not the octopus. In this case, the octopus had a bifurcated (split) arm and still used it effectively, just like any other arm. That tells us the nervous system didn’t treat it as a mistake—it figured out how to make it work.” Kenna Hughes-Castleberry is the science communicator at JILA (a joint physics research institute between the National Institute of Standards and Technology and the University of Colorado Boulder) and a freelance science journalist.

Researchers from the National University of Singapore (NUS) have developed a 3D printed, self-powered mechanoluminescent (ML) photonic skin designed for communication and safety monitoring in underwater environments. The stretchable device emits light in response to mechanical deformation, requires no external power source, and remains functional under conditions such as high salinity and extreme temperatures. The findings were published in Advanced Materials by Xiaolu Sun, Shaohua Ling, Zhihang Qin, Jinrun Zhou, Quangang Shi, Zhuangjian Liu, and Yu Jun Tan. The research was conducted at NUS and Singapore’s Agency for Science, Technology and Research (A*STAR). Schematic of the 3D printed mechanoluminescent photonic skin showing fabrication steps and light emission under deformation. Image via Sun et al., Advanced Materials. 3D printing stretchable light-emitting skins with auxetic geometry The photonic skin was produced using a 3D printing method called direct-ink-writing (DIW), which involves extruding a specially formulated ink through a fine nozzle to build up complex structures layer by layer. In this case, the ink was made by mixing tiny particles of zinc sulfide doped with copper (ZnS:Cu), a material that glows when stretched, with a flexible silicone rubber. These particles serve as the active ingredient that lights up when the material is deformed, while the silicone acts as a soft, stretchable support structure. To make the device more adaptable to movement and curved surfaces, like human skin or underwater equipment, the researchers printed it using auxetic designs. Auxetic structures have a rare mechanical property known as a negative Poisson’s ratio. Unlike most materials, which become thinner when stretched, auxetic designs expand laterally under tension. This makes them ideal for conforming to curved or irregular surfaces, such as joints, flexible robots, or underwater gear, without wrinkling or detaching. Encapsulating the printed skin in a clear silicone layer further improves performance by distributing mechanical stress evenly. This prevents localized tearing and ensures that the light emission remains bright and uniform, even after 10,000 cycles of stretching and relaxing. In previous stretchable light-emitting devices, uneven stress often led to dimming, flickering, or early material failure. Mechanical and optical performance of encapsulated photonic skin across 10,000 stretch cycles. Image via Sun et al., Advanced Materials. Underwater signaling, robotics, and gas leak detection The team demonstrated multiple applications for the photonic skin. When integrated into wearable gloves, the skin enabled light-based Morse code communication through simple finger gestures. Bending one or more fingers activated the mechanoluminescence, emitting visible flashes that corresponded to messages such as “UP,” “OK,” or “SOS.” The system remained fully functional when submerged in cold water (~7°C), simulating deep-sea conditions. In a separate test, the skin was applied to a gas tank mock-up to monitor for leaks. A pinhole defect was covered with the printed skin and sealed using stretchable tape. When pressurized air escaped through the leak, the localized mechanical force caused a bright cyan glow at the exact leak site, offering a passive, electronics-free alternative to conventional gas sensors. To test performance on soft and mobile platforms, the researchers also mounted the photonic skin onto a robotic fish. As the robot swam through water tanks at different temperatures (24°C, 50°C, and 7°C), the skin continued to light up reliably, demonstrating its resilience and utility for marine robotics.

Toward electronics-free underwater communication While LEDs and optical fibers are widely used in underwater lighting systems, their dependence on rigid form factors and external power makes them unsuitable for dynamic, flexible applications. In contrast, the stretchable ML photonic skin developed by NUS researchers provides a self-powered, adaptable alternative for diver signaling, robotic inspection, and leak detection, potentially transforming the toolkit for underwater communication and safety systems. Future directions include enhanced sensory integration and robotic applications, as the team continues exploring robust photonic systems for extreme environments. Photonic skin integrated into gloves for Morse code signaling and applied to robotic fish and gas tanks for underwater safety monitoring. Image via Sun et al., Advanced Materials. The rise of 3D printed multifunctional materials The development of the photonic skin reflects a broader trend in additive manufacturing toward multifunctional materials, structures that serve more than a structural role. Researchers are increasingly using multimaterial 3D printing to embed sensing, actuation, and signaling functions directly into devices. For example, recent work by SUSTech and City University of Hong Kong on thick-panel origami structures showed how multimaterial printing can enable large, foldable systems with high strength and motion control. These and other advances, including conductive FDM processes and Lithoz’s multimaterial ceramic tools, mark a shift toward printing entire systems. The NUS photonic skin fits squarely within this movement, combining mechanical adaptability, environmental durability, and real-time optical output into a single printable form.

We may earn a commission from links on this page.In 2023, I decided to update my Apple Watch after consistently failing to wear my Series 4 for a number of years. I sold that one on Poshmark and began looking at newer models to find one with enough features to convince me to actually wear it. I opted to get a Series 8, although the Series 9 had just been released, as I was buying two: one for my mom and one for myself. As it turns out, that was a great decision.If you're searching for a new wearable or considering upgrading yours, you might also be wondering which of the older Apple Watch models is still useful today. My Series 8 is holding up beautifully three years after it was introduced, so I'm a big proponent of using older devices as long as possible. But not all Apple Watches will work as well as the Series 8 does in 2025. Don’t buy a watch Apple doesn’t support anymoreWe have to draw the line somewhere: Seven of Apple's watches are no longer supported, meaning they won't receive any software or security updates anymore. In addition, you run the risk that the watch will no longer be compatible with your iPhone or certain apps. In short, you shouldn't buy a watch that Apple doesn't support. That includes the following:Apple Watch Series 0Apple Watch Series 1Apple Watch Series 2Apple Watch Series 3Apple Watch Series 4Apple Watch Series 5Apple Watch SE (first-gen) While the company does currently support the Series 6, it is next in line to join this list. It's not clear when that will happen, but you can be sure it will. We'll see next week—when Apple reveals watchOS 26—whether the watch will be supported another year. If not, it'll be stuck on watchOS 11 for good.Performance and other generational Watch improvementsThere are considerations for older Apple Watch models that extend beyond their ability to simply run the latest operating system. With each generation, improvements are made in some form or another. For instance, the Series 4 introduced the ECG sensor, while the Series 6 introduced the blood oxygen sensor (though Apple had to disable the feature for the Series 9 and Ultra 2 in the U.S. due to a lawsuit). The Series 7 charges faster than its predecessors, and Apple has included fast charging on most watch models since (sorry, Apple Watch SE users).In general, each Apple Watch is faster than the last. Apple tends to put its newest S-Chip—the Apple Watch's processor—in its latest watch series. Simply put, a newer S-chip gives you a faster, more productive product. The Series 6 has an S6 chip, Series 7 has S7, and so on until you hit the Ultras. (The first-generation Ultra has an S8 chip like the Series 8, while the Ultra 2 has an S9 chip like the Series 9.)While there are some core features all currently supported watches share—like workout and swim tracking, sleep tracking, Apple Pay, ECG scanning, and the ability to read and respond to messages—newer models also each have some of their own special advancements and upgrades. Here's a brief list:The Series 7 introduced faster charging, a larger display, and more durable screen.The Series 8 brought temperature sensing, crash detection, and a low-power mode for conserving battery (as did the second-gen Apple Watch SE).The Series 9 debuted new gesture controls, on-device Siri access, more precise location tracking in Find My, and a display with double the brightness of the Series 8.The first-gen Apple Watch Ultra introduced a more durable titanium casing, custom shortcuts to apps and modes via the Action button, a depth gauge and water temperature sensor, more accurate GPS, a 36-hour battery life, and an emergency siren.The Apple Watch Ultra 2 introduced a display with a maximum brightness of 3,000 nits and on-device media playback. The Series 10 introduced the largest display available on a standard Apple Watch and faster charging. If you see a feature you absolutely need in a particular watch model, you'll have to spring for it. But if you just want something for core Apple Watch tasks, you can start to consider older options. Apple's watch comparison site can be a helpful tool for identifying different features among models. Battery degradation All tech degrades to some extent and the Apple Watch is no different—particularly when it comes to the battery. While there are ways to mitigate the problem, over time, the lithium-ion battery powering your wrist computer won't last as long as it used to. That might be a bigger issue than your watch's ability to download and support a new operating system. Apple's warranty doesn't cover batteries that wear down from normal use, and charges $99 for the repair, which you could instead put towards the purchase of a new watch. There is one exception: Battery service is free if you have AppleCare+ and your watch's battery holds less than 80% of its original capacity. You need to take your watch in to an Apple Store or service provider to have it tested. My watch was pre-owned, and while I have no way of knowing if it has its original battery, my battery life has not declined substantially in the two years I've been using it daily. I primarily use mine to track my workouts, vitals, and sleep, which means it's always running. I charge it while I'm in the shower and occasionally for a few minutes before bed, and that's about it. On an average day of constant notifications, mine lasts me a bit longer than the advertised 18-hour mark. Because I have little interest in the small improvements offered by the Series 9 and Series 10—like extra brightness, larger screen size, performance bumps, and advanced cycle tracking—the battery life is what would (or will) compel me to upgrade in the future, but for now, I have not noticed any problems. I asked my mom if she's noticed any battery degradation on hers, since I bought it at the same time and place as mine, and she said no. She uses hers to track walking workouts, talk on the phone, and monitor her sleep and vitals, too.Stick with the Series 7 or newerThoroughly consider which of the features on newer models are actually important to you before making any buying decision and, if you can, stay above a Series 7. The Series 6 is still functional, but, again, it's a matter of time until the company stops acknowledging that one completely. For now, I have been pleasantly surprised by how well my Series 8 has held up for two years. Its touchscreen has never faltered, the external buttons function perfectly, it syncs to all of my apps and devices with no problem, and it does exactly what I need it to do—which is to tell me how many steps I'm taking and how hard I'm exerting myself at the gym. If you're in the market for a smart watch, I see no reason that an older version shouldn't be considered, as long as it still runs the latest operating system. You can save a chunk of change by sourcing an older model from the resale or refurbished markets and put that money away for when Apple drops something super revolutionary in the wearable space. Apple doesn't sell anything below a Series 10 or SE directly anymore, so if you want a 6, 7, 8, or 9, you'll have to check the resale and refurbished markets. You'll definitely save some money that way (a new Series 10 starts at $399, though it can be found on sale, and the refurbished Series 8 I got is selling right now for $219).

Fruit flies don't naturally enjoy the taste of cocaine. Credit: Deposit Photos Get the Popular Science daily newsletter💡 Breakthroughs, discoveries, and DIY tips sent every weekday. In a world first, scientists at the University of Utah have engineered fruit flies susceptible to cocaine addiction. But as strange as it sounds, there are potentially life-saving reasons for genetically altering the insects to crave the drug. The novel biological model could help addiction treatment therapies development and expedite research timelines. The findings are detailed in the Journal of Neuroscience. As surprising as it may sound, humans have a lot in common with fruit flies. In fact, we share around 70–75 percent of the same genes responsible for various diseases, as well as many of the same vital organs. Researchers have relied on the insects for genetic studies for years, especially for investigating the biological roots of certain addictions like cocaine abuse. This is due in large part to the fruit fly’s quick life cycle and its comparatively simple genetic makeup. But while scientists have administered the drug to the bugs in the past, there’s always been a small problem. “Flies don’t like cocaine one bit,” Adrian Rothenfluh, the study’s senior author and an associate professor of psychiatry, said in a statement. Even when previously introduced to cocaine, Rothenfluh’s team noted that the insects routinely opted for pure sugar water over sugar water laced with cocaine. Study first author Travis Philyaw theorized the reason may reside in a fly’s sense of taste that is found on their legs. “Insects are evolutionarily primed to avoid plant toxins, and cocaine is a plant toxin,” Philyaw explained. “They have taste receptors on their ‘arms’—their tarsal segments—so they can put their hand in something before it goes in their mouth, and decide, ‘I’m not going to touch that.'” After confirming that cocaine activates a fruit fly’s bitter-sensing taste receptors, Rothenfluh and Philyaw switched off those nerves. Once deactivated, there was little to stop the flies from developing a cocaine habit. These modified flies were subsequently introduced to sugar water infused with a low concentration of cocaine. Within 16 hours, the insects indicated a preference for the drug-laced drink. “At low doses, they start running around, just like people,” said Rothenfluh. “At very high doses, they get incapacitated, which is also true in people.” Now that researchers know how to breed the modified fruit flies, they can more easily study how cocaine addiction evolves in the body. Not only that, but they can do so on a much faster timeline by analyzing hundreds of genes at a time. “We can scale research so quickly in flies,” said Philyaw. “We can identify risk genes that might be difficult to uncover in more complex organisms, and then we pass that information to researchers who work with mammalian models.” From there, scientists can identify treatment targets that help link to human therapy options. “We can really start to understand the mechanisms of cocaine choice, and the more you understand about the mechanism, the more you have a chance to find a therapeutic that might act on that mechanism,” explained Rothenfluh.

Heydar Aliyev Center | © Olivier Blanchette via Unsplash In contemporary architectural discourse, the building envelope is no longer a passive partition but a dynamic interface capable of interaction, regulation, and adaptation. Amid rising environmental complexity and performance demands, composite materials are emerging as enablers of this transformation. Their potential goes far beyond lightweight strength; composites are redefining what intelligence means in architectural materiality. As the industry pivots toward energy-conscious design, real-time responsiveness, and multi-functional skins, composites provide structural solutions and performative systems. In this context, the envelope becomes a site of intelligence. From Passive Shells to Active Systems For centuries, architectural skins served primarily as barriers, blocking weather, enclosing space, and symbolizing permanence. But the 21st century demands more. We require façades that filter air and light, mediate thermal flux, integrate sensors, and generate power. Traditional materials, limited by monolithic performance and weight, have struggled to adapt. Composites, by contrast, are inherently systemic. They are engineered layers rather than singular substances. Through the integration of fibers and matrices, composites enable architectural envelopes that perform structurally while accommodating embedded systems such as thermal insulation, acoustic control, impact resistance, and photoreactivity. These characteristics make them prime candidates for high-performance envelopes in buildings and infrastructure alike. In the Qatar Integrated Railway Project, composite roofing and FRP façade panels were employed to meet the demands of the harsh desert environment. This solution reduced structural loads and improved thermal performance while ensuring long-term durability in a climate defined by extremes. Performance Layering and Embedded Intelligence What distinguishes composites from conventional materials is their capacity to combine multiple performance layers in one unified system. Instead of applying insulation, waterproofing, and cladding in sequence, a composite panel can consolidate these into a single prefabricated, high-performance element. A compelling example is the Eco Casa in Australia, designed by Ian Wright, which used frameless DuFLEX composite panels. The result was an environmentally conscious home with significantly reduced material waste, enhanced thermal performance, and minimized emissions. These outcomes demonstrate how composites offer design efficiency and ecological responsibility. The capacity for prefabrication and integration is particularly valuable in settings where labor conditions, transportation logistics, or weather exposure make traditional multi-layered construction inefficient or impractical. Composites with a Nervous System: Sensing the Built Environment Recent innovations in smart composites extend these capabilities further. By embedding fiber-optic or piezoresistive sensors into composite assemblies, architects and engineers can develop building skins that sense stress, temperature changes, humidity, or vibration in real-time. These responsive façades can feed data into building management systems, enabling performance optimization or alerting maintenance teams to signs of wear or structural fatigue. This functionality has been successfully explored in transport infrastructure. The King Abdullah High-Speed Rail Station in Saudi Arabia used 27-meter composite sandwich panels to span vast distances with minimal support. The lightweight system reduced the need for extensive reinforcement while enabling thermal and mechanical performance in a climate that demands resilience. Such examples are foundational to a future in which architecture does not merely resist the environment but interprets it. Formal Freedom Meets Functional Responsiveness Guangzhou Opera House | © Scarbor Siu via Unsplash Beyond embedded intelligence, composites also expand formal expression. Their moldability, especially with parametric design and digital fabrication, allows for envelopes that curve, fold, and morph in unattainable ways with conventional rigid materials. The Guangzhou Opera House, designed by Zaha Hadid Architects, is a defining example. Advanced composite assemblies that merged structural demands with formal ambition enabled its seamless curvatures and sharp transitions. These systems supported high-precision details and complex geometries while reducing material weight and installation complexity. This freedom extends to smaller-scale yet equally ambitious projects. At the Tilburg School for VAVO, translucent composite panels embedded with knitted textiles reference local craft while offering thermal performance and design cohesion. Such examples show that intelligence in architecture includes cultural sensitivity as well as technical adaptability. Toward Circular and Regenerative Envelopes The sustainability potential of composites is often overlooked. While early generations relied heavily on fossil-derived materials, newer systems use bio-based resins, natural fibers like flax and basalt, and recyclable matrices that fit into circular design models. Composite panels can now be designed for disassembly, repurposing, or reintegration into new construction, minimizing waste and conserving embodied energy. The Pasarela de Almuñécar in Spain exemplifies this ethos. As the world’s longest carbon-fiber walkway, it replaced heavier materials and extended structural lifespan while reducing maintenance. The project signals how composites can fulfill both technical and ecological ambitions. Efforts to embed digital tracking into panels, such as RFID tags, also support long-term monitoring and facilitate reuse planning. This vision aligns with emerging concepts like material passports, which will play a critical role in lifecycle accountability.

First is the challenge of integration with legacy materials such as concrete, stone, or steel. Connection detailing requires careful coordination to ensure structural continuity and thermal performance. Second is the perception of cost. While composites may require a higher upfront investment, their lower maintenance demands, improved energy performance, and reduced structural requirements often result in favorable long-term economics. Finally, regulatory frameworks continue to evolve. Building codes have been slow to reflect the unique properties of composites, although this is changing as standardization increases and successful pilot projects proliferate. A Vision for the Future: Architecture as Adaptive Intelligence Composites are not merely substitutes for traditional materials. They represent a paradigm shift in how we understand performance, integration, and the role of material in space-making. As architecture becomes increasingly data-driven, climate-responsive, and energy-conscious, the intelligent envelope will become the norm rather than the exception. Composites make this future feasible by offering structural capability, aesthetic freedom, environmental stewardship, and embedded intelligence within a single engineered solution. From high-speed rail terminals to cultural landmarks, these materials are shaping a new kind of architecture that listens, learns, and evolves. It is no longer sufficient for architecture to stand still. The next generation of buildings must adapt, interact, and perform. Composites make that future tangible.
