Triboelectric Nanogenerators (TENGs) are emerging electronic devices that allow mechanical energy to be converted into electrical energy, positioning them as integral components in the next generation of wearable Internet of Things (IoTs) systems. These devices play a crucial role in efficiently managing the power for small-scale electronics. Consequently, TENGs present significant application potential in self-powered sensor technology. Given the increasingly constrained global energy resources, researchers have focused much attention toward developing self-powered systems. This study introduces a self-powered motion sensing system leveraging a TENG (CNT-TENG) composed of a Thermoplastic Polyurethane (TPU) film doped with Carbon Nanotubes (CNTs) and Polytetrafluoroethylene (PTFE) as friction materials. The fabricated CNT-TENG with exceptional durability exhibited a maximum power density of 13.5 mW/m at a resistance of 98 MΩ. Beyond its ability to reliably power a sports timer, the CNT-TENG can also sensitively monitor human movement in real time as a self-sustaining sensor. This innovative design is capable of effectively utilizing human kinetic energy, offering seamless integration with motion sensing applications in sports and wearable technologies.
摩擦纳米发电机(TENGs)是新兴的电子设备,可将机械能转化为电能,使其成为下一代可穿戴物联网(IoT)系统的重要组成部分。这些设备在有效管理小型电子设备的电源方面发挥着关键作用。因此,摩擦纳米发电机在自供电传感器技术中具有巨大的应用潜力。鉴于全球能源资源日益紧张,研究人员将大量注意力集中在开发自供电系统上。本研究介绍了一种自供电运动传感系统,该系统利用了一种由掺杂有碳纳米管(CNTs)的热塑性聚氨酯(TPU)薄膜和聚四氟乙烯(PTFE)作为摩擦材料组成的摩擦纳米发电机(CNT-TENG)。所制备的具有卓越耐久性的CNT-TENG在98 MΩ的电阻下表现出13.5 mW/m的最大功率密度。除了能够可靠地为运动定时器供电外,CNT-TENG还可以作为一个自我维持的传感器实时灵敏地监测人体运动。这种创新设计能够有效利用人体动能,与运动和可穿戴技术中的运动传感应用实现无缝集成。
