|ENGINEERS have developed an electronic skin that could one day restore a sense of touch to people with prosthetic limbs.|
Built out of nanowires and dubbed the "e-skin", the electronic material is so pressure-sensitive that it mimics the sensitivity of human touch.
"The idea is to have a material that functions like the human skin, which means incorporating the ability to feel and touch objects," said nanotechnologist and research leader, Ali Javey, from the University of California, Berkeley.
To build the skin, the researchers printed small squares of nanowires onto a thin film. Each square of nanowires was integrated with an electric switch, before pressure-sensitive rubber was then placed on top of the film to provide the sensitivity.
