Abstract

An actuator device has an electroactive polymer actuator and an integrated piezoelectric transformer. At least a secondary side of the integrated piezoelectric transformer shares a piezoelectric electroactive polymer layer with the electroactive polymer actuator, so that lower external voltages can be applied to the actuator device. A diode is connected between the secondary side of the integrated piezoelectric transformer and the electroactive polymer actuator.
