Soft materials, and flexible electronics are creating robotic "skin."
Millions of nerve endings in human skin feel heat and touch. It's a great detector and responder to the outside environment.
These technologies may allow people remotely control robots and "feel" their signals.
Ravinder Dahiya, a professor of electronics and nanoengineering at the University of Glasgow
says 1980s touch sensors resembled flesh. Flexible sensor arrays appeared in the mid-1980s. Infrared sensors and detectors were installed on 1960s-era Kapton.
Compared to organic skin, their capacities were primitive. The 2000s saw softer, more flexible, and stretchy materials and technologies
Dahiya's electronic skin's data processing was inspired by human skin, according to two Science Robotics publications released this month. Using transistors and capacitors we can design a PNS.
