Abstract
An actuator device has an electroactive polymer actuator () and an integrated piezoelectric transformer () whose primary side () and secondary side () are formed from different electroactive polymer materials. At least the secondary side () of the transformer shares a piezoelectric electroactive polymer layer () with the electroactive polymer actuator, so that lower external voltages can be applied to the device.
