Carbon neutrality is a global green energy revolution meaning that the carbon dioxide can make ends meet. However, with the mushroom of the fifth generation wireless systems (5G) and the Internet of Things (IoT), it is a great challenge for powering the ubiquitous distributed devices, because the battery production and high overhead maintenance may bring more carbon emissions. Here, we present wearable biosensors for real-time sweat analysis and body motion capture based on stretchable fiber-based triboelectric nanogenerators (F-TENG). The F-TENG is made of stretchable conductive fiber (Ecoflex coating with polyaniline (PANI)) and varnished wires. Based on the coupling effect of triboelectric effect and enzymatic reaction (surface-triboelectric coupling effect), the wearable biosensors can not only precisely sense the motion states, but also detect glucose, creatinine and lactate acid in sweat in real-time. Importantly, the wearable devices can self-drive without any external power source and the response against glucose, creatinine and lactate acid can be up to 103%, 125% and 38%, respectively. On this basis, applications in biosensing and wireless communication have been demonstrated. This work exhibits a prospective potential application of F-TENG in IoT for diverse use.
碳中和是一场全球绿色能源革命，意味着二氧化碳可以收支平衡。然而，随着第五代无线系统（5G）和物联网（IoT）的兴起，为无处不在的分布式设备供电是一项巨大的挑战，因为电池生产和高额的维护费用可能会带来更多的碳排放。在这里，我们提出了基于可拉伸纤维基摩擦纳米发电机（F-TENG）的实时汗液分析和身体运动捕捉可穿戴生物传感器。F-TENG 由可拉伸导电纤维（涂有聚邻苯二胺（PANI）的 Ecoflex）和涂漆电线制成。基于摩擦电效应和酶反应的耦合效应（表面摩擦耦合效应），可穿戴生物传感器不仅可以精确感知运动状态，还可以实时检测汗液中的葡萄糖、肌酸和乳酸。重要的是，可穿戴设备可以在没有任何外部电源的情况下自行驱动，对葡萄糖、肌酸和乳酸的响应分别可达 103%、125%和 38%。在此基础上，已经展示了在生物传感和无线通信中的应用。这项工作展示了 F-TENG 在物联网中的应用前景，适用于各种用途。
