摘要

電源、續航力問題是未來可撓式電子產品的一大罩門。可行的辦法之一便是從人體自身的身體運動來擷取能量，並轉換成電能。人體總是包覆著紡織物，因此，開發可以轉換人體運動能的紡織物是有潛力的方式。在此篇文章中，將介紹一種可以擷取人體運動能的紡線，一段由發電紡線製成的6.5 英吋×4.5 英吋摩擦奈米發電機布料，可以產生200 伏特的開路電壓，以及200 微安的短路電流。該布料可用於擷取身體各部位的運動能量，包含手肘伸展、膝蓋伸展、走路、拍打等，轉換的電能可以直接驅動發光二極體，也可持續驅動智慧型手錶。除了當能源擷取元件提供電源給電子設備，該紡線為基的摩擦奈米發電機，也可以做為自驅動的感測器，並且與為控制系統作整合。我們相信利用紡線製成的摩擦能源擷取元件可以解決可撓式電子的電力問題。

Power source is one of most challenge issues of flexible electronics. One of promising solution is harvest energy from human-body motion and transfer body-motion energy to electrical energy. In order to efficiently scavenge energy from human motion, to develop a textile-based nanogenerator is most promising way; this is because the fact that human body is always covered by clothing. Here, a thread-based triboelectric nanogenerator is demonstrated. A elastic textile (6.5 inch × 4.5 inch) fabricated by the device can generate 200 V of open-circuit voltage and 200 μ A of short-circuit current. The textile can be used for harvesting various kinds of body motion energy, including elbow flexion and extension, keen flexion and extension, walking, tapping, and so forth. The generated electricity can directly light up tens of LEDs and sustainably drive a commercial smart watch. Not only acting as a power supplier, the thread-based triboelectric nanogenerators can use as self-powered sensors and integrate with microcontrollers for more sophisticated wireless applications. It is believed the thread-based nanogenerators can pave the path for the energy sources of flexible electronics.
