Abstract:
Modeling and experimental verification of energy harvesting for a composite cantilever beam with a piezoelectric patch are presented. Finite element and lumped-parameter models are developed for open- and closed resistive circuit. A basic in-house circuit is compared to a commercial one in terms of power output. Results indicate good performance of the lumped-parameter models. The effect of frequency on the harvested power is also presented.
