Abstract

Embodiments of actuators having an active member including a polymer having a surface, an electrolyte coupled to the surface, and an electrolyte are provided. Actuators which, when an electrical potential is applied across the electrolyte between the active member and the counter electrode, exert force per unit area of at least 10 MPa are described. Particular designs utilizing stretch aligned conducting polymers as active members are discussed.
