Title:
MULTI-FREQUENCY PIEZOELECTRIC ENERGY HARVESTER
Document Type and Number:
WIPO Patent Application WO2004038820
Kind Code:
A3
Abstract:
An energy harvesting device is provided. The energy harvesting device includes structural members covered with piezoelectric material resonating at different primary frequencies. As the structure to which the energy harvesting device is secured vibrates over a range of frequencies, more than one member resonates or is close to resonance. As such, multiple members work simultaneously to create electrical energy.
