Abstract : The spontaneous self-sustained flapping of a piezo-electric flag placed in a fluid flow may be used to produce electricity. This abstract presents a study of the coupled dynamics of such a fluid-solid-electric system, and analyzes the influence of resonant output circuits on the harvesting efficiency. Both numerical and experimental investigations show enhancement of harvesting efficiency induced by resonant circuit.
