磁電發電機透過壓電效應與磁致伸縮效應產生的磁電效應，搭配振動結構作為材料相對位移之媒介，使其成為一磁電發電機，其發電機制為可同時利用振動與磁場兩不同環境源來產生換能作用，相較於傳統上利用單一發電機制，磁電發電機可進一步增強發電機之電壓輸出和轉換效率。本論文並分析比較多層磁電元件在不同磁鐵位置下的發電情形，藉以優化輸出的發電量。;In this paper, a vibration energy harvester using magnetoelectric (ME) transducer is proposed. The ME energy harvester is a multilayer structure which is composed of piezoelectric material and magnetostrictive material. The working principle of the ME harvester is scavenging two different forms of energy, including vibration and magnetic field. Compared to conventional energy harvester using single mechanism, the dual-mode energy harvesting can further enhance the voltage output and conversion efficiency.
