Abstract

This paper presents a hybrid energy harvester using piezoelectric (PZT) and electromagnetic (EM) technologies. A mathematical model of the output power for this generator was developed. Experiments were carried out to verify the numerical analysis. The theoretical results were in good agreement with the experimental results. The experimental results showed that the maximum output power of the separate PZT and EM energy harvesters were 0.667 mW and 0.32 mW, while that of the hybrid harvester was 0.845 mW under the vibration acceleration of 9.8 m/s2 at 66 Hz. It shows that the hybrid energy harvester can effectively increase the output power.
