'Super skin' powered by stretchable solar cells

'Super skin' powered by stretchable solar cells: "Last September we covered a story about a pressure-sensitive artificial skin developed at Stanford University that is so sensitive it can 'feel' the weight of a butterfly. As part of a goal to create what she calls 'super skin,' Stanford researcher Zhenan Bao is now giving the artificial skin the ability to detect chemical and biological molecules"
