穿戴式裝置發展至現今，電池續航力是面臨的最大且急需解決的問題之一。微型能源採集器可轉換周遭環境之能源為可供應之電源，並且不受使用壽命的限制，提供穿戴式裝置能源可靠之解決方案。人體作動可產生之頻率約為1Hz~2Hz之間，所以本論文提出一微型低頻穿戴式振動能源採集器，其由一頻率105Hz之靜電能源採集器為基礎並降低其共振頻率並希望尺寸限制於1cm×1cm×0.5cm以內來達到人體可產生之振動頻率範圍並能夠為型化將人體可產生之振動能轉為電能提供給電子產品使用。此設計提升了能源採集器可使用的頻率區間且尺寸為8mm×8mm×2.054mm符合預期之微型化目標。取用人類一般走路可達之頻率2Hz, 每一循環可產生能量0.0803 μJ及平均功率0.27 μW，提升了能源採集之功率。

In the development of wearable device, battery life is one of the most urgent problems and harvesting the kinetic or thermal energy into power provides a reliable solution to power supply. We proposed a micro electrostatic vibration energy harvester that can transform low frequency human motion in 1-2 Hz into electrical energy. The size of electrostatic vibration energy harvester in this thesis is 8mm×8mm×2.054mm, the mass , the stiffness of spring 0.022 N/m, and the natural frequency is 1.664 Hz. When the external vibration frequency is 1.664 Hz with amplitude 1200 μm, this energy harvester can provide 0.27 μW.
