Nature, Published online: 05 February 2025; doi:10.1038/d41586-025-00340-8A miniaturized electromechanical device has been developed that attaches directly to the skin, utilizing it as an elastic, energy-storing element for delivering touch stimuli. This wireless, conformable interface enables sensory substitution for individuals with sensory impairments, such as problems with sight, sense of balance or foot orientation during walking.
