Abstract:
An energy harvesting system includes a composite structure that has a first spring, a piezoelectric structure, and a proof mass. The piezoelectric structure and the proof mass are mounted on the first spring. The composite structure has a natural frequency of vibration. The natural frequency of vibration of the composite structure is automatically adjustable.
