Abstract

Wearable triboelectric nanogenerators (TENGs) have emerged as a transformative technology for converting low-frequency mechanical energy into electrical power, offering promising applications in electronic skins, human–machine interfaces, and advanced healthcare systems. However, achieving structural robustness and multifunctionality in thermal regulation remains a persistent challenge for TENG-based skin electronics. This deficiency compromises the charge transfer efficiency and diminishes user comfort during prolonged wear. This study introduces a novel thermally regulating triboelectric nanogenerator (TR-TENG) in the form of a bilayer electronic textile (e-textile) fabricated through a semi-bonding assembly approach. The e-textile comprises two distinct layers: nonwoven styrene-ethylene-butylene-styrene (SEBS) textiles loaded with highly reflective and electronegative polyvinylidene fluoride-trifluoroethylene (PVDF-TrFE) nanoparticles (NPs) and polyvinyl alcohol (PVA) fibers embedded with emissive and electropositive SiO₂ NPs. These layers are merged via hot-press needle punching, creating a flexible, permeable yet robust interface capable of dual functionalities—enhanced solar reflection and efficient infrared emission—while maintaining stable triboelectric performance. When utilized as a skin-attachable self-powered motion sensor, this e-textile provides a remarkable passive radiative cooling effect and high-fidelity recognition of both high-frequency and subtle motions (swallowing, running, breathing, etc.). This TR-TENG e-textile presents a breakthrough in self-powered and comfortable electronics for next-generation healthcare technologies.

用于皮肤上热调节和自供电运动监测的具有半粘合双层的坚固摩擦电子纺织品

可穿戴摩擦电纳米发电机（TENGs）是一种将低频机械能转化为电能的变革性技术，在电子皮肤、人机界面和先进的医疗保健系统中有着广阔的应用前景。然而，在热调节中实现结构稳健性和多功能性仍然是基于teng的皮肤电子器件的持续挑战。这种缺陷损害了电荷传递效率，并在长时间的磨损中降低了用户的舒适度。本研究介绍了一种新型的热调节摩擦电纳米发电机（TR-TENG），其形式为双层电子纺织品（e-textile），通过半键合组装方法制成。电子纺织品包括两个不同的层：含有高反射性和电负性聚偏氟乙烯-三氟乙烯（PVDF-TrFE）纳米粒子（NPs）的非织造苯乙烯-乙烯-丁烯-苯乙烯（SEBS）纺织品，以及嵌入有发射性和电正性SiO2纳米粒子的聚乙烯醇（PVA）纤维。这些层通过热压针冲孔合并，创造了一个灵活、可渗透且坚固的界面，具有双重功能-增强的太阳反射和有效的红外发射-同时保持稳定的摩擦电性能。当用作可贴在皮肤上的自供电运动传感器时，这种电子纺织品提供了显着的被动辐射冷却效果，并对高频和细微运动（吞咽、跑步、呼吸等）进行高保真识别。这款TR-TENG电子纺织品为下一代医疗保健技术提供了自供电和舒适电子产品的突破。图形抽象
