The stereotype of the clumsy robot may soon become a thing of the past thanks to ongoing research at the University of California, Berkeley, where a team of engineers has created a thin and interactive sensor network that can be layered onto the surfaces of virtually any shape. The device gives out immediate feedback via an LED light when touched, and could be used to create smart bandages that monitor vitals in a patient in real time, wallpapers that act as touchscreens, or even to give humanoid robots that elusive "human touch."
