技術說明

開發一種能同時產生高頻振動及微小電能之壓電元件系統，導入於需要使用振動及電能之產業應用，並選定具代表性之微放電加工及物理治療應用為例。此新型壓電元件主要是結合兩件壓電陶瓷振動子配合周邊機構完成，將輸入電能於第一個壓電陶瓷振動子利用逆壓電效應原理轉換為高頻振動輸出，銜接於後之第二個壓電陶瓷振動子利用正壓電效應原理將輸入振動機械能轉換為電能，這部份具有能源再利用之意義，若系統設計適當而相較於微放電加工及物理治療兩種應用所需之總能量低，則更有節能效果。此新型壓電元件係一體設計可以同時提供兩種能量及性能輸出，其系統結構設計更為簡單且經濟。另嘗試導入微機構設計於放電端以獲得更佳之微放電加工及電療效果，達到技術創新之指標。(US) A new development makes use of a specific piezoelectric-driven device that is able to produce both high-frequency vibration and low electric power simultaneously for any likely applications. Implementation of such device to the chosen application examples of Micro Electric Discharge Machining and Physical Therapy are described. This piezoelectric-driven device mainly consists of two pieces of ceramics actuators. With power input to the first actuator to oscillate, the connected second one makes use of the transmitted mechanical vibration energy to generate electricity, which has the meaning of renewable energy. In case the energy expanse is less than the general use for both applications, the developed device has the advantage of energy saving. Moreover, this device is compact and economic because it is built with both functions in one set.
