Graphene’s greatness comes from its flexibility, both figurative — you can also 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 making a stretchy transistor from the carbon allotrope. The trick was accomplished by first layering sheets of graphene on copper foil and bonding all of it to a rubber substrate. To finish the transistor channels were etched onto its surface, then electrodes and gate insulators manufactured from ion gel were printed onto the device. What resulted was a transistor that may stretch as much as five percent without losing any electrical efficiency, and the plan is to extend its elasticity through continued research. Sustain the coolest work, fellas, we cannot stay up for our flexible phone future .
