In the last few years, scientists and engineers have begun to borrow design principles from the paper arts of origami and kirigami (ori=fold, kiru=cut). This multidisciplinary approach is already proving its potential in everything from medicine to satellite engineering. Graphene, an extraordinarily strong atom-thick sheet, is the ideal starting material for bringing these design ideas down to the nanoscale. We have developed a technique to lift graphene and manipulate it like a sheet of paper in aqueous solution. This allows us to measure the out-of-plane bending stiffness of graphene, a fundamental mechanical property that has never been conclusively measured at the micron scale. We see a stiffness orders of magnitude higher than the atomic-scale value, and show that this surprising result can be explained by theories of thermally induced fluctuations. We then apply designs from the paper art of kirigami to create three-dimensional structures and moving parts. We demonstrate robust stretchable electrodes and extraordinarily resilient hinges, and show that we can control graphene devices directly with micromanipulators or remotely with magnetic fields and lasers. Graphene kirigami's extraordinary mechanical and electrical properties make it promising for a variety of applications, from force sensors to biocompatible electrical readouts. This simple but powerful approach to creating graphene metamaterials promises diverse, resilient moving parts at the nanoscale.
