There are plenty of robot arms out there, but what about the skin to cover them in? A new kind of piezotronic transistor mesh could make for robotic skin that’s as sensitive as your own is, covered in thousands of tiny mechanical hairs.
The inventor of the technology, Zhong Lin Wan from Georgia Tech, says it has immediate applications in human-machine interfaces. It could for example be used to capture electronic signatures by recording the distinctive force an individual applies while signing. In due time, Wan expects the pressure sensor arrays could equip robotics and prosthetics with a human-like sense of touch.
