本論文提出一寬頻的微型振動發電機，回顧調整頻寬以及增加頻寬的方法讓發電機的工作頻寬增加，使得能應用的振動環境更加廣泛。接著介紹基礎理論，以及利用導電銀膠製作線圈結構的方法與流程。後面進行簡單的模態分析，討論線圈的支撐柱高低對共振頻率的影響。 實驗量測三種不同修剪長度的元件，分析其共振頻率、開路電壓及輸出功率，並討論在不同輸入振幅造成的影響。最後三種不同修剪長度中達到最大頻寬的元件，其各層頻寬分別為3.63 Hz以及3.59 Hz，串聯後頻寬達到11.29 Hz。功率方面在各層的共振頻率以及最大功率傳輸的狀況下，各層線圈的最大的平均功率分別有41.01 nW及49.54 nW。 ;This paper proposes a wide-bandwidth micro vibration generator. Conductive silver paste is used to make the coil structures on the substrate. Electromagnetic induction coverts the vibration energy into electrical energy. Simulation is conducted to study the effect of the height of the coil′s connection pillar on the resonance frequency. Three generators with different coil lengths are characterized. Resonance frequency, open-circuit voltage, and output power are measured. For the generator with maximum bandwidth, the maximum output powers and bandwidths are 41.01 nW and 3.63 Hz for coil 1 and 49.54 nW and 3.59 Hz for coil 2. The bandwidth for two coils connecting in series is 11.29 Hz.
