Scientists are one step closer to equipping robots with a finer sense of touch. According to Phys.org, engineers at the University of California, Berkeley, have developed a new sensor network on flexible plastic. The electronic skin lights up when touched and gives off a brighter light as more pressure is put on it. The visual component could help robots "see" how much pressure they are putting on an object. Chuan Wang, who helped create the "e-skin," believes it could have benefits beyond robotics. He imagines an "e-skin bandage" applied to a patient's arm that can help constantly monitor blood pressure and pulse rates. The team of researchers are currently trying to engineer the e-skin to respond to temperature and light.
