BRENT: Researchers have found a new way to take advantage of the atom-thick “wonder material” graphene: use it for origami. Strictly speaking, actually, it’s kirigami, the version of the paper-folding art that uses cutting as well — a bit like making paper snowflakes. With carefully-planned folds and snips, researchers led by Cornell University’s Melina Blees have created microscopic simple machines and structures: springs, pyramids, hinges and more.
Graphene is a lattice of carbon atoms that’s about as thin as anything can be yet also strong, flexible and conductive. Scientists and engineers are continually coming up with new ways to use it, from super-strong silk to water filters — even if no one has quite figured out how to make the stuff in bulk just yet.
