Available, effectively converting low-frequency vibration into available electricity, triboelectric nanogenerator (TENG) is always research hot nowadays. However, the enhancing effect of the existing methods for the output have all sorts of drawbacks, i.e., low efficiency and unstable, and its practical applications still need to be further explored. Here, leveraging core-shell nanoparticles Ag@SiO doping into tribo-materials generates the surface plasmon effect to boost the output performance of the TENG. On one hand, the shell alleviated the seepage effect from conventional nanoparticles; on the other hand, the surface plasmon effect enabled the core-shell nanoparticles to further boost the output performance of TENG. We circumvent the limitations and present a TENG whose output power density can be up to 4.375 mW/cm. Points is that this article novelty investigate the high-performance TENG applicating for traditional Chinese medicine and develop a pratical self-powered acupuncture system. This technology enables rapid, routine regulation of human health at any age, which has potential applications in nearly any setting across healthcare platforms alike.
摩擦纳米发电机（TENG）能够有效地将低频振动转化为可用电能，是目前的研究热点。然而，现有提高其输出的方法存在各种缺点，如效率低且不稳定，其实际应用仍需进一步探索。在此，将核壳纳米颗粒Ag@SiO掺杂到摩擦材料中可产生表面等离子体效应，以提高TENG的输出性能。一方面，壳层减轻了传统纳米颗粒的渗漏效应；另一方面，表面等离子体效应使核壳纳米颗粒能够进一步提高TENG的输出性能。我们克服了这些限制，展示了一种输出功率密度可达4.375 mW/cm的TENG。重点是，本文创新性地研究了应用于中医的高性能TENG，并开发了一种实用的自供电针灸系统。这项技术能够在任何年龄快速、常规地调节人体健康，在几乎所有医疗保健平台的任何场景中都具有潜在应用。
