In view of the problem that piezoelectric and electromagnetic energy harvester could not output high voltage and current at the same time, a hybrid piezoelectric and electromagnetic energy harvester was designed,based on which theoretical model was derived,and the expressions of voltage,current,vibration amplitude and output power were given.A optimization program was put forward according to the simulation analysis for the hybrid piezoelectric and electromagnetic energy harvester by Ansys and Ansoft software. Finally, the piezoelectric,electromagnetic and hybrid piezoelectric and electromagnetic energy harvesters were compared through experiments.The results showed that the output power of hybrid piezoelectric and electromagnetic energy harvester increased by 118% and 38% compared with piezoelectric and electromagnetic energy harvesters and the 3 dB bandwidth increased by 67% and 25% under the acceleration of 0.6g (g=9.8 m/s2).
