Nanotube Springs in Super-stretchy Skin-like Sensor
Using carbon nanotubes bent to act as springs, Stanford researchers have developed a stretchable, transparent skin-like sensor. The sensor can be stretched to more than twice its original length and bounce back perfectly to its original shape. It can sense pressure from a firm pinch to thousands of pounds. The sensor could have applications in prosthetic limbs, robotics and touch-sensitive computer displays. Darren Lipomi, a postdoctoral researcher in Chemical Engineering and Zhenan Bao, associate professor in Chemical Engineering, explain their work.
