'Smart skin' mimics the sense of touch

A team of scientists from the United States and China may have taken a big step forward in mimicking the sense of touch.  They’ve created a “smart skin” that can sense pressure in the same range as a human fingertip.

The “skin” uses bundles of vertical zinc oxide nanowires, consisting of about 8,000 touch-sensitive transistors.  Each of the transistors can independently produce an electrical signal when placed under pressure, comparable to the human sense of touch.

According to the researchers, this is a fundamentally new technology that could be used in a broad range of areas, including the development of artificial skin capable of “feeling” activity on the surface and the ability to provide robots with a more adaptive sense of touch.
