本研究 製作出 具有 拉伸性的 低頻 振 動發電 機 ,由兩片具有平面螺旋導電線圈 的彈性薄膜與銣鐵硼磁鐵組成,整個元件體積約為 12×50×14 mm3。 本研究使 用 PDMS製成彈性薄膜以及可隨容器體積變化的液態金屬作為發電機主要材料。 利用電磁感應原理將振動源轉換為磁場變化,使液態金屬線圈產生感應電流 與常 見使用剛性材料製作的 微型發電機相比, 元件可以承受較大的應變。 此論文對兩種 形式的薄膜進行研究,第一種形式的薄膜在頻率為 26 Hz時,產生最大的平均開路 電壓 0.55 mV,平均功率為 5.2 nW。第二種形式之薄膜在頻率為 20 Hz時,平均開 路電壓 0.165 mV 平均功率 0.4325 nW。;A stretchable low-frequency vibration generator, which consists of two elastic membranes with planar spiral conductive coils and neodymium magnets is fabricated. The entire element volume is about 12×50×14 mm3 . The principle of electromagnetic induction is used to convert the vibration source into a magnetic field change, which causes the liquid metal coil to generate an induced current. Compared with the common micro-generators made of rigid materials, the proposed design can withstand larger strains. Two types of the generators are characterized. The first type produces a maximum average open circuit voltage of 0.55 mV and an average power of 5.2 nW at a frequency of 26 Hz. The second type has an average open circuit voltage of 0.165 mV and an average power of 0.4325 nW at a frequency of 20 Hz.
