Polymer skin adds sensory capabilities to prosthetics
DOI: 10.1063/PT.5.028489
MIT Technology Review : A “smart” skin laden with integrated sensors has been developed for use on prosthetic limbs to allow the wearer to sense heat, pressure, and moisture. In a recent paper published in Nature Communications, researchers in Korea and the US describe a polymer covering they have created that comprises networks of sensors made of ultrathin gold and silicon. Not only do the sensors provide touch similar to that of a normal hand but they also have the ability to stretch like human skin. In addition, integrated actuators make the artificial skin feel warm to the touch. The technology is innovative; connecting it to the human nervous system is the next challenge.
