摩擦电纳米发电机作为一种很有前途的能源获取技术，近年来得到了迅速的发展。然而，基于完全柔性和环境友好的Tengs的研究仍然有限。在这里，首次展示了一种同时具有高柔韧性、可回收性和环境友好性的水凝胶基摩擦电纳米发电机(水凝胶-腾)。标准的水凝胶-腾在10M欧米茄的负载电阻下可以产生2 mW的最大输出功率。管状水凝胶-Teng可以从各种人体运动中获取机械能量，包括弯曲、扭曲和拉伸。此外，该系统还可以作为自供电传感器来检测人体运动。此外，本研究所使用的聚乙烯醇水凝胶是可回收的，有利于制造可再生的Teng。更新后的水凝胶-腾的开路电压可以达到原始输出电压的92%。这一研究将为以环境友好的方式开发灵活的能源和自供电运动传感器提供潜在的途径。
Triboelectric nanogenerators (TENGs), as a promising energy harvesting technology, have been rapidly developed in recent years. However, the research based on fully flexible and environmentally friendly TENGs is still limited. Herein, for the first time, a hydrogel-based triboelectric nanogenerator (Hydrogel-TENG) with high flexibility, recyclability, and environmental friendliness simultaneously has been demonstrated. The standard Hydrogel-TENG can generate a maximum output power of 2 mW at a load resistance of 10 M Omega. The tube-shaped Hydrogel-TENG can harvest mechanical energy from various human motions, including bending, twisting, and stretching. Furthermore, the system can serve as self-powered sensors to detect the human motions. Additionally, the utilized Polyvinyl Alcohol hydrogel employed in this study is recyclable to benefit for fabricating the renewable TENG. The open-circuit voltage of renewed hydrogel-TENG can reach up to 92% of the pristine output voltage. This research will pave a potential approach for the development of flexible energy sources and self-powered motion sensors in environmentally friendly way.
