Materials: Making circuits that are stretchable could open up a host of new applications, from medical sensors to video-game controllers
ELECTRONIC circuits that stretch like elastic bands or expand like balloons sound not just fanciful, but impractical. Yet a little flexibility could be useful, at least in some situations: for medical implants and sensors, for example. IMEC, a Belgian research group, has recently made a start on this idea by building tiny electric wires that can stretch to twice their length without breaking.
