Abstract

This paper presents a new hybrid piezoelectric-electromagnetic vibration-powered generator (HPVG). An electromagnetic generator and a piezoelectric generator are combined as an integrated HPVG. An input-output mathematical model describing the coupling of the mechanical filed, electrical field, and magnetic field in the HPVG is presented. The resonant frequency, the output voltage waveforms, and the output power have been studied. The HPVG has a much higher power output compared with a single piezoelectric generator or an electromagnetic generator of the same dimension.
