目前地球上能開採能源有原油及天然氣，但終究還是有徹底用完的一天，因此世界各先進國家正尋找及發展各種可能取代現今使用能源。現今可利用或能採集的能源，包含振動能、電磁波、汽車機械、水力、海洋中的波浪、洋流以及人類的運動且可分類為高功率及小低功率的振動能源。本文藉以能量捕獲做為發想將工廠既有持續轉動馬達加入機械敲擊壓電陶瓷達到能量轉換目的，透過振動方式進而產生低電流及低功率電能，由於當下所產生的電能無法直接供應於低功率負載使用，故先將所產生的電能存於充電電池組中，讓電池組以短時間不斷電的情況下儲存供應電能，再交替進行供電及充電於低功率元件上。使用太陽能感光裝置捕獲太陽能，是利用太陽能光感值去控制低功率元件；本研究中兩種實驗皆以實際軟硬體測試，可達到短時間最基本供電及控制狀況。對電子紙而言則是質輕便、長時待機低耗量運用在壓電陶瓷輸出電壓後將實際電壓值及電池組供電切換狀態全程顯示於電子紙上證明實驗結果正確性，另外對於太陽能感光裝置得到光感值做判斷，驅使電子紙能顯示本實驗所設定的特定訊息，以證明所顯示結果之正確性。

Currently, on Earth, the extractable energy sources include crude oil and natural gas. However, there will eventually be a day when they are completely depleted. As a result, advanced countries around the world are actively seeking and developing various alternative energy sources to replace the ones currently in use. Some of the currently available and harvestable energy sources include vibrational energy, electromagnetic waves, automobile mechanics, hydropower, waves and ocean currents, as well as human movement. These energy sources can be categorized into high-power and low-power vibrational energy. This paper explores the concept of energy harvesting by incorporating mechanical impacts on piezoelectric ceramics into the existing continuously rotating motors of factories to achieve energy conversion. Through this vibrational approach, low electrical current and low-power electrical energy can be generated. However, the generated electricity cannot directly supply low-power loads. Therefore, the produced electricity is first stored in a battery pack, allowing the batteries to continuously store and supply electricity to the low-power components in a cyclical manner. In addition, solar energy capture using photovoltaic devices is employed to control the low-power components based on solar irradiance values. In this research, both experiments are tested using real hardware and software to achieve the basic supply of electricity and control conditions in a short period. For electronic paper, the experiment utilizes the output voltage from the piezoelectric ceramics to switch between the actual voltage value and the battery pack's power supply status, demonstrating the accuracy of the experimental results on the electronic paper. Furthermore, the photovoltaic device is used to obtain light sensitivity values for determining specific messages displayed on the electronic paper, thus confirming the accuracy of the displayed results.
