Paper, as one of the most important inventions of mankind, is still widely used in our daily life. In this study, the paper is explored as a platform for power sources based on the universally known triboelectric friction. A novel paper triboelectric nanogenerator (P-TENG) was successfully developed, which could harvest mechanical energy from ambient sources and generate considerable electrical energy. The maximum power density of the P-TENG reached 53 W m. In addition, the P-TENG possesses a natural advantage of being able to be integrated within a book, and thus can effectively convert mechanical energy from the action of turning book pages into electricity. When turning a book page, the output voltage and current of the P-TENG were obtained to be about 400 V and 0.17 mA, respectively. This generated electricity could directly light up 80 commercial white light-emitting diodes (LEDs) connected in series without any energy storage process. The white LEDs powered by the P-TENG can provide sufficient illumination for reading printed text in darkness. This research provides a promising solution for developing paper-based self-powered electronic systems.
纸作为人类最重要的发明之一，在我们的日常生活中仍然被广泛使用。本研究基于普遍存在的摩擦起电现象，探索将纸作为电源平台。成功研制了一种新型的纸摩擦纳米发电机（P-TENG），它可以从环境能源中收集机械能并产生可观的电能。P-TENG 的最大功率密度达到 53 W m。此外，P-TENG 具有能够集成在书本内的天然优势，因此可以有效地将翻书页的机械能转化为电能。当翻书时，P-TENG 的输出电压和电流分别约为 400 V 和 0.17 mA。所产生的电能无需任何储能过程即可直接点亮 80 个串联的商用白色发光二极管（LED）。由 P-TENG 供电的白色 LED 可为在黑暗中阅读印刷文本提供足够的照明。这项研究为开发基于纸张的自供电电子系统提供了一个很有前途的解决方案。
