Graphene's greatness comes from its flexibility, both figurative -- you can make everything from transparent speakers to stain resistant pants with the stuff -- and literal. And now researchers in Korea have given us another pliable graphene product by creating a stretchy transistor from the carbon allotrope. The trick was accomplished by first layering sheets of graphene on copper foil and bonding it all to a rubber substrate. To complete the transistor channels were etched onto its surface, then electrodes and gate insulators made of ion gel were printed onto the device. What resulted was a transistor that could stretch up to five percent without losing any electrical efficiency, and the plan is to increase its elasticity through continued research. Keep up the good work, fellas, we can't wait for our flexible phone future.
