Abstract
This paper presents a new mathematical model of the output power by taking the secondary piezoelectric effect of a piezoelectric-electromagnetic hybrid energy harvester into account. The numerical results show that compared with the single piezoelectric power generator, the optimized external load increases the sytem power output of the hybrid energy harvester by 13.3%. Furthermore, compared with the external load optimization, the damping parameter matching improves the peak output power of the hybrid energy harvester by 23%. Hybrid energy harvesting experiments were carried out to verify the numerical analysis. The experimental results are in accordance with the theoretical results.
