振動能量獵能系統 (Vibration Energy Harvester (VEH)) 是將振動的機械能轉換成電能的一種裝置，其振動源來自各種機械振動，例如車子的振動、吊橋的晃動甚至是飛行器下游的振動流場等。在本研究裡，吾人提供了一組雙片彈性鋼的壓電能量獵能系統，利用兩片彈性鋼的形變及拍打所產生的振動，輔之以壓電片 (Piezo-Patch) 進而產生電能，並和儲能設備加以結合，提出了綠能整合的完整解決方案(Total solution)。
吾人採用實驗的方法，建立了此系統的實作模型，研究此系統的動態響應、平均功率輸出、能量收集效率等。吾人也提出了一簡單儲能裝置，將振動所收集的能量儲存於電容及鎳氫電池中。因為壓電片所產生的電能為交流電(Alternating Current)，所以需要利用橋式全波整流器(Rectifier)將交流電轉換成直流電(Direct Current)加以應用。
此系統在未來可裝置在機翼的Trailing edge或旋翼機的主旋翼下方，讓飛行時所產生的氣流造成系統振動，加以收集其機械能轉換成電能，提供額外的電力給飛行中的飛機，此研究也建立了一綠能整合的完整解決方式的基礎模型，並展示其相關應用。

The objective of vibration energy harvesting (VEH) is to convert the energy of vibration motion such as car vibration, suspension bridge vibration, or any kind of mechanical vibration energy into electric energy. In this study, a total solution of Double Elastic Steel Sheet(DESS)piezo-vibration energy harvester base excited mechanical system is proposed to take advantage of the vibrational energy of two long elastic steels oscillation and tapping motion. The present work provides an energy harvesting, the electric power converting and an energy storing a total solution for the VEH system. The experimental method was employed and the analytical model was built in the proposed VEH system. The dynamic response, average power output, energy harvesting efficiency of the proposed harvester were studied. The output voltage of the VEH system was verified by a theoretical model and numerical results.  
  The vibration induced electric power was stored by the capacity installed in this VEH system. The capacity with a rectifier can transfer the output of AC voltage into DC voltage. This model can be applied on the trailing edge of a wing or on the downstream of any rotary wing aircraft main rotor. The vibration airflow behind the wing trailing edge or the downstream of the helicopter main rotor provides a continuing shedding vibration energy for the DESS system and thus generates the electric power. This study implements this model and shows its practical applications.
