Crumpled graphene could power future stretchable electronics

When someone crumples a sheet of paper, that usually means it's about to be thrown away. But researchers have now found that crumpling a piece of graphene "paper" -- a material formed by bonding together layers of the two-dimensional form of carbon -- can actually yield new properties that could be useful for creating extremely stretchable supercapacitors to store energy for flexible electronic devices.
