為提供目前微小系統元件對具自生性之微型能量供應器的需求,本研究提出一個可轉換機械能為電能輸出之微發電元件,以壓電原理為基礎,藉由機械振動再經由壓電效應而產生電能。本研究先透過理論分析建立一個完整的壓電式微發電機電能轉換模式,接著進行設計、製作與測試。接著以有限元素法設計並計算結構之共振頻率,取得其最大能量之輸出效率,再以壓電陶瓷燒結技術製作壓電元件,並貼負在金屬薄板上,製作所需之微發電器,最後以振動產生器配合線路佈局取得輸出電壓,以實驗驗證理論之能量輸出。
經過實際之製作與發電量測結果發現,各結構在某一頻率會有最大發電電壓且此頻率與以ANSYS所分析各結構之自然共振頻率相當接近,由此可推斷此頻率為各結構之實際自然共振頻率,並證實如理論分析,當外界之振動頻率等於發電結構之自然共振頻率時會有最大發電量。
To fulfill the increasing self-power demanding of the embedded and remote microsystems, theoretical and experimental study of a piezoelectric vibration-induced micro power generator that can convert mechanical vibration energy into electrical energy is presented. A complete energy conversion model regarding the piezoelectric transducer is discussed first. To verify the theoretical analysis, two clusters of transducer structures are fabricated. The piezoelectric lead zirconate titanate (PZT) material that has better energy conversion efficiency among the piezoelectric materials is chosen to make of the energy conversion transducer. The desired shape of the piezoelectric generator with its resonance frequency in accordance with the ambient vibration source is designed by finite element analysis (FEA) approach.
Conducting wires and load resistor are soldered on the electrodes to output and measure the vibration induced electrical power. Experimental results shows that the maximum output voltages are generated at the first mode resonance frequencies of the structure. It is also found from the experimental results that the induced voltage is irrelevant to the width of the structure but is inverse proportion to the length of the structure. It takes 7 minutes to charge a 10,000 mF capacitors array to a 7 V level. The total amount of electricity and energy stored in the capacitors are 0.7 Coulomb and 2.45 J, respectively. The experimental results are coincidence with the theoretical analysis.
