Piezoelectric Skin
July 23, 2013 | Terry Sharrer
By creating arrays of thousands of piezotronic transistors with zinc oxide nanowires embedded in a polymer, engineers at Georgia Tech have made an artificial skin that has the touch sensitivity of a human fingertip. This would provide a significant improvement in robots and prosthetics, but the material also could be used in various sensors that conceivable track vital signs, movement, physical rehabilitation, and measure more serious situations involving impact.
