Abstract
A rotary actuator for applying torque to a crank with respect to a member. The rotary actuator has a substantially planar sheet of anisotropic conducting polymer, portions of which are activated in temporal sequence to produce rotation of the crank with respect to the axis of the crank. Actuation is achieved by contraction of successive portions of the sheet as electrical current causes differential strain in the sheet.
