Abstract
Described herein is a generator with an electroactive polymer transducer. The transducer has a capacitance that varies with deflection of a polymer included in the transducer. The generator also includes a generator circuit, coupled to the electroactive polymer transducer, that includes a capacitor. The generator circuit is configured such that the capacitor collects electrical energy from the electroactive polymer transducer in response to a change in capacitance of the polymer.
