    Abstract: 近來由於再生能源議題不斷受到重視,將環境中的潛在能源轉換為電能,已 是自我供電系統中不可或缺的一環,其中以振動能量轉換為電能為國際諸多實驗 室訂為研究重點。理論上有諸多機制可將振動能轉換為電能,但以壓電效應為轉 換媒介之發電器因為壓電材料具有高機電耦合效應,優良的品質因子,並且在微 小化過程中可配合半導體製程和積體電路整合等多項好處,近年來已成為機械能 與電能之間的轉換媒介首選。其中鐃鈸(Cymbal )型壓電換能器因具有高有效 壓電係數、高輸出力、高靜水壓優值、高位移、高加速靈敏度及體小量輕等優點, 因此為壓電發電器的首選元件。 本專題為『鐃鈸型壓電陶瓷換能器設計及其在發電地板的應用』,預計執行期 限二年,計畫內容為: 第一年:高效能鐃鈸型(Cymbal)壓電換能器特性設計、分析與模擬。 第二年:壓電地板機械結構與電子電路系統之整合設計使成為一能量擷取系統。

    Recently, renewable energy issues have received international attentions in many nations. Converting the potential energy of environment into electricity has become an integral part of self-powered system. Therefore, the transformations between the vibration energy and electrical energy are set as the key topics in research issues among the national laboratories all over the world. There are many theoretical mechanisms for the vibration energy to be converted into the electrical energy, but the piezoelectric effect is the best candidate for the conversion of generators. Because piezoelectric material posses a number of benefits such as high electromechanical coupling effect, good quality factor, and devices miniaturized by semiconductor manufacturing processes and integrated circuits, etc., therefore it has become a material of choice for the conversion between the mechanical energy and electrical energy. A piezoelectric cymbal transducer is the top component chosen for a piezoelectric generator due to high effective piezoelectric coefficient, high output power, an excellent high hydrostatic pressure , high-displacement, high acceleration sensitivity and light weight, etc., The research topics is 『Development of Cymbal Type Pieoelectric Transducer and Implementation on Power Floor for Energy Harvesting』, which is expectedly implemented in two years: First year: Development and analysis of a high-performance cymbal piezoelectric transducer. Second year: Integration of the mechanical structure of a Piezoelectric power floor and an electronic circuit system for Energy Harvesting .
