適用於堆疊式壓電發電裝置的快速儲能電路研究

為了解決全球暖化的問題，全球對於再生能源的開發與應用正如火如荼地展開中，其中廣設太陽能板以及興建風力發電廠等，無疑地是目前常見再生能源開發的主力。但是，上述兩種再生能源的發展主力往往需要投入大量的資金，更要選擇合適的場所才能發揮其效益。另一方面，一種新興再生能源–壓電發電裝置，它不但可以取自周遭環境的振動能源，更不受地域與時間條件限制，即便是無陽光與無風力的環境地域，這種–壓電發電之能量依然可以很容易被擷取而獲得。有鑑於此，本研究配置了完整的實驗流程，首先利用本實驗室開發出的最佳幾何結構的堆疊式壓電發電裝置作為壓電能源轉換的核心結構。藉由此核心結構設計出不同層數以及不同擺放方式的壓電發電裝置之實驗。此外，我們也設計出合適的儲能系統將堆疊式壓電發電模組所轉換的電能有效儲存起來，以實現開發堆疊式壓電發電之再生能源的目標。實驗證據顯示，透過兩組最佳結構設計的三層堆疊式壓電發電模組其輸出功率可達5.175mW。同時，兩組三層堆疊式壓電發電裝置所產生的電能透過能量儲存系統能夠使15mAh的鎳氫電池於40小時內充飽。

For solving the globe warming problem, the action of creating renewable energy by wildly building the solar and wind power plants has been undoubtly to become two major developments. Unfortunately, the above two major efforts accordingly rely on a huge budget as well as a suitable working place to fully display their function efficiency. On the other hand, a newly developed technique by piezoelectric power generator to create renewable energy has caused much attraction since its friendly adoption; nevertheless the surrounding environment is lack of sunlight and wind. Basing on the statement mentioned in the above, the piezoelectric element is the core of the piezoelectric energy conversion system in this study, which utilizes the external force on piezoelectric module to generate an available output power. At the beginning, we have developed the optimal geometrical structure of stacked piezoelectric power generation device as the core structure. We use this core structure to design the experiments of the different layers and different arrangement of the piezoelectric power generation device. In addition, we also design a suitable energy storage system to the stacked piezoelectric power generation modules convert electrical energy is effectively stored, to achieve the objectives of the development of stacked piezoelectric generator of renewable energy. Evidence indicated that the two-set of optimal three-layer stackable piezoelectric power generation devices could obviously achieve an instantaneous output power (5.175 mW). At the same time, a 15 mAh Ni-MH battery could be fully-charged within forty hours by utilizing the two set of optimal three-layer stackable piezoelectric power generation devices constituting with energy storage system.
