MC10‘s Roozbeh Ghaffari and a team of researchers from the US and Korea have developed artificial skin for prosthetics that mimics the sensitivity of real skin. Its silicon and gold sensors detect pressure, moisture, heat and cold. It is elastic enough for users to stretch and move a bionic hand’s fingers as they would real fingers. According to Ghaffari, “If you have these sensors at high resolution across the finger, you can give the same tactile touch that the normal hand would convey to the brain.” A paper detailing the research was published in Nature earlier this month.
