Spray-on nanotube aids skin-like sensor device

Stanford University researchers recently demonstrated a new stretchable, transparent skin-like sensor developed using carbon nanotubes that bend and act as springs, according to a university news release. The flexible sensor "can be stretched to more than twice its original length and bounce back perfectly to its original shape," the researchers reported. Given its intended application in prosthetic limbs, the new sensor technology is said to be capable of sensing pressure from a firm pinch up to thousands of pounds.
