Engineers at UC Berkeley have created a system of sensors on flexible plastic that reacts to pressure by lighting up. The new "e-skin" recognizes the amount of pressure and responds with a brighter or dimmer light accordingly.
The technology can be used to give robots a more precise sense of touch and also might be used to create interactive wallpapers or automobile dashboards.
What differentiates the e-skin from other touch sensor networks is its flexibility and interactivity, says Chuan Wang, associate professor of electrical and computer engineering at Michigan State University. Wang participated in the research as a post-doctoral student at UC Berkeley, as part of a research team led by Ali Javey. Because the e-skin is pliable, it can be applied as a laminate to other surfaces.
