In this paper, we have developed a high-performance graphene electrothermal actuator (ETA). The fabrication method is easy, fast, environmentally friendly, and suitable for preparing both large-size miniature ETAs. When applied with the driving voltage of 65 V, ETA achieves large bending angle 270° fast response 8 s recovery process costs 19 s. deformation reversible can be precisely controlled by voltage. A simple robotic hand prepared using single hold object, which more than ten times weight itself. By virtue its large-strain, response, easy-to-manufacture, believe that has tremendous potential in extensive applications involving biomimetic robotics, artificial muscles, switches, microsensors macroscopic microscopic fields.
