Abstract:
An actuator includes a stack including: an elastomer layer; and an elastic electrode disposed on each surface of the elastomer layer, in which the stack is subjected to a pre-strain of 50% or more at least in one direction. The stack may have a round tubular shape with the elastic electrodes disposed on opposite surfaces of the elastomer layer in a radial direction of the stack.
