本研究成功利用液態金屬直寫製程，製作出可配合環形磁鐵運作之旋轉發電機線圈，並且調整PDMS之厚度減少密封層與黏合層改善感應電壓，實現可用於可伸縮電子元件、印刷電路製作之技術。配合製程差異更改線圈直寫路徑方式，運用繞組因數描述繞組匝數增加之實際電壓疊加情形。並以最大電壓做為比較依據，選擇最佳匝數以規畫實際直寫路徑，同時達成堆疊多層線圈並製作相同兩組放置磁鐵兩側以增加線圈發電量，經由半波整流不須經過倍壓電路即可驅動鍺電晶體。;In this study, the liquid metal direct writing process was successfully used to fabricate a rotating generator coil that can operate with a ring magnet, and the thickness of the PDMS was adjusted to reduce the sealing layer and the adhesive layer to improve the induced voltage and realize the application of scalable electronic components and technology of printed circuits. We change the direct writing path of the coil according to the process difference, and use the winding factor to describe the actual voltage superposition of the increase in the number of winding turns. We take the maximum voltage as a comparison basis and choose the best number of turns to plan the actual direct writing path. At the same time, we place two sets of coils on both sides of the magnet to increase the power generation. Lastly, the germanium transistors can be driven by half-wave rectification without going through a voltage doubler circuit.
