Electronic skin will help amputees to sense environment

(Cross-posted on Jeepakistan.blogspot.com)

Scientists from Technion-Israel Institute of Technology have developed a sort of electronic skin having flexible sensors operating on low voltage that would help amputees to sense touch, humidity and temperature.

This e-skin could be attached to prosthetic limbs and would help them to sense the environment. It is a major breakthrough as the current devices detect only touch.

In this research, scientists utilized gold particles and a kind of resin that is about 10 times more sensitive to touch than the traditional e-skin devices.
