Switched Crumpling of Graphene Could Lead to Nano-Muscles

One property of graphene, an atom-thick lattice of carbon, is that it easily "crumples", just like paper. This is usually a disadvantage, as long as a flat sheet is desired. But it can also be turned in a very useful mechanism, if it can be switched on and off to act as a nano-scale muscle.
