To develop new materials for robotics, Chinese scientists have developed graphene-based actuators that convert electricity into motion (ACS Nano, DOI: 10.1021/nn3006812). In robots, actuators act like muscles, driving the movement of mechanical limbs. Most electromechanical actuator materials, such as ceramics and conductive polymers, respond slowly, require a lot of power, or provide very little force. To make speedier, . . .
