Recently, wearable, self-powered, active human motion sensors have attracted a great deal of attention for biomechanics, physiology, kinesiology, and entertainment. Although some progress has been achieved, new types of stretchable and wearable devices are urgently required to promote the practical application. In this article, targeted at self-powered active human motion sensing, a stretchable, flexible, and wearable triboelectric nanogenerator based on kinesio tapes (KT-TENG) haven been designed and investigated systematically. The device can effectively work during stretching or bending. Both the short-circuit transferred charge and open-circuit voltage exhibit an excellent linear relationship with the stretched displacements and bending angles, enabling its application as a wearable self-powered sensor for real-time human motion monitoring, like knee joint bending and human gestures. Moreover, the KT-TENG shows good stability and durability for long-term operation. Compared with the previous works, the KT-TENG without a macro-scale air gap inside, or stretchable triboelectric layers, possesses various advantages, such as simple fabrication, compact structure, superior flexibility and stability, excellent conformable contact with skin, and wide-range selection of triboelectric materials. This work provides a new prospect for a wearable, self-powered, active human motion sensor and has numerous potential applications in the fields of healthcare monitoring, human-machine interfacing, and prosthesis developing.
最近，可穿戴、自供电的有源人体运动传感器在生物力学、生理学、运动学和娱乐领域引起了广泛关注。尽管已经取得了一些进展，但迫切需要新型的可拉伸可穿戴设备来推动实际应用。在本文中，针对自供电有源人体运动传感，设计并系统研究了一种基于肌内效贴布的可拉伸、柔性且可穿戴的摩擦电纳米发电机（KT-TENG）。该装置在拉伸或弯曲过程中均能有效工作。短路转移电荷和开路电压与拉伸位移和弯曲角度均呈现出良好的线性关系，使其能够作为可穿戴自供电传感器用于实时人体运动监测，如膝关节弯曲和人体手势。此外，KT-TENG在长期运行中表现出良好的稳定性和耐久性。与先前的工作相比，内部无宏观气隙或可拉伸摩擦电层的KT-TENG具有多种优势，如制造简单、结构紧凑、柔韧性和稳定性优异、与皮肤的贴合性良好以及摩擦电材料的选择范围广泛。这项工作为可穿戴、自供电的有源人体运动传感器提供了新的前景，并在医疗监测、人机接口和假肢开发等领域具有众多潜在应用。
