Energy, information, and materials are the three main factors required for the survival and development of modern humankind, with energy being the cornerstone of all development. In recent years, self-powered devices have received widespread attention. As a new generation device, Triboelectric nanogenerators (TENGs) assembled from flexible materials possess the characteristics of flexible design, low-cost, stable output performance, etc., and can be widely used in wearable and self-powered medical detection sensors of human body. In this paper, flexible bromobutyl rubber (BIIR) and PET were used as friction materials, and assembled into arched vertical contact-separation triboelectric nanogenerators following various film formation and surface roughening treatments. The treatment and assembly methods of the friction materials were studied in order to obtain the best power generating effects. In addition, due to the biocompatibility and intrinsic antibacterial property of BIIR films, the fabricated triboelectric nanogenerator was also applied to wearable self-powered sensor equipment, proving its potential in the fields of identification and gait analysis.

能源，信息和材料是现代人类赖以生存和发展的三个主要因素，能源是一切发展的基石。近年来，自供电设备受到广泛关注。由挠性材料组装而成的摩擦电纳米发生器（TENGs）作为一种新一代设备，具有设计灵活，成本低廉，输出性能稳定等特点，可广泛用于人体可穿戴和自供电的医学检测传感器。本文将柔性溴化丁基橡胶（BIIR）和PET用作摩擦材料，并在进行各种成膜和表面粗糙化处理后，组装成拱形垂直接触分离式摩擦电纳米发电机。为了获得最佳的发电效果，研究了摩擦材料的处理和组装方法。此外，由于BIIR薄膜的生物相容性和固有的抗菌性能，制造的摩擦电纳米发电机也被应用于可穿戴式自供电传感器设备，证明了其在识别和步态分析领域的潜力。
