本文探討一根表面貼附4塊壓電材料之Timoshenko懸臂樑模型，首先以有限元素法為基礎，由靜態平衡方程式得到單位有限元素之解，接下來利用元素的堆疊探討整體鋁樑的頻率與位移圖，再利用Newmark法計算出此樑在外力下所產生的感應電壓，接下來設計一組能量截取電路，將感應電壓有效的儲存下來。
當整體量受到外力而形變，壓電片會產生感應電壓，本論文內設計一組電壓截取電路，將感應電壓轉換成能夠使用的直流電，經過整流、濾波、穩壓等等步驟，得到平穩的直流電。

In this thesis, this research aims to investigate the voltage generated from the piezoelectric materials via the vibration of the Timoshenko Beam through four piezoelectric layers mounted on the Timoshenko beam. The finite element technique and Newmark’s method were adopted to calculate the displacement and the induced voltage. An energy harvesting circuit is designed to store the electric current coming from the piezoelectric material. The energy harvesting circuit includes the filter circuit, rectifier circuit, voltage regulator, and charge device. In order to store the energy effectively, the OrCad software was adopted to simulate the circuit and an experiment was taken.
