Two separate teams of researchers have developed pressure-sensing devices that could improve the sense of touch of prosthetics and allow surgeons to better maneuver equipment during less-invasive surgeries. Experts at Stanford University have developed an organic electronics-based system that is flexible and 1,000 times more sensitive than human skin. Meanwhile, scientists at the University of California, Berkeley, have devised a low-power system that uses arrays of nanowire transistors.
