Abstract
Methods and systems are provided for combined direct current and alternating current activation of electroactive polymer devices. The combined direct current and alternating current activation may increase force generation compared to activation using direct current alone. For example, a method for actuating an electroactive polymer device may include providing the electroactive polymer device. The electroactive polymer device may include a first electrode and a second electrode electrically coupled to an electroactive polymer. The method may include applying a direct current across the electroactive polymer via the first and second electrodes. The method may include applying an alternating current across the electroactive polymer. The direct current and the alternating current may be effective to cause actuation of the electroactive polymer device.
