Abstract:As nonlinear technology allows piezoelectric energy harvesting to obtain a wider vibration frequency and a higher output voltage, this paper proposed a new nonlinear hybrid piezoelectric and electromagnetic energy harvester based on nonlinear vibration. The new nonlinear hybrid piezoelectric and electromagnetic energy harvester could be equivalent to a qualityspringdamper vibration system with nonlinear stiffness, the total average output power of the energy harvester was deduced. In 0.6 g harmonic excitation, the distance between magnets was 2.5 mm, 3 mm,4 mm, the nonlinear hybrid piezoelectric and electromagnetic energy harvester was measured. The results showed that as the distance between magnets decreased with increasing gravity, the resonant frequency of the nonlinear energy harvester was reduced, and the 3 dB bandwidth increased.
