Nature : A new self-folding material made of layers of graphene oxide has been developed for use in robotics and other technologies. Porous to water molecules, the graphene-based paper folds out as it absorbs water from the air and folds back in on itself when the water is released by exposure to heat or near-IR light. In their paper published in Science Advances, Hongzhi Wang of China’s Donghua University and his colleagues say they were able to use the material to create various machines—a device that folds into a box, a hand that can grab and lift objects five times heavier than itself, and a microrobot that walks.
