Self-Folding Minirobots Possible with Origami-Inspired Graphene

Origami-inspired graphene paper that can fold itself could be used to create anything from miniature robots to artificial muscles, according to a new study. Scientists from Donghua University in China have demonstrated that gently heating a sheet of graphene paper, which is extraordinarily strong (about 200 times stronger than steel by weight), could make it fold into a device that is able to walk forward and backward. The research could help scientists develop self-folding structures and device
