MiniTouch device enables amputees to feel natural temperatures

Researchers have developed a device, MiniTouch, that allows amputees to feel natural temperature sensations through their prosthetic limbs. The device reproduces temperatures from 20C to 40C, enabling amputees to perceive warmth or coolness and distinguish between materials. Tested on a 57-year-old amputee, it improved his ability to discriminate between objects and increased his accuracy in various tasks. The device is non-invasive, easily personalized, and relatively inexpensive. The team aims to create a single wearable system for multiple sensations.
