Triboelectric nanogenerators (TENGs) are state-of-the-art devices that generate electricity through the coupling effect of triboelectrification and electrostatic induction by harvesting mechanical energy. This study aims to boost the electrical performance of a TENG that harvests biomechanical energy to power wearable and portable electronic devices by employing a simple and inexpensive method based on GnPs. For this purpose, I have designed and produced a vertical-contact-separation mode TENG suitable for biomechanical energy harvesting using tribonegative materials Polyvinylidene difluoride (PVDF)/ Polyetheretherketone (PEEK) veil and tribopositive materials Polyethylene oxide (PEO)/ Glass and Nylon 6.6 nanofibers. The surface of the PEEK veil is coated with a PVDF solution with excellent tribonegativity and ferroelectric polarization properties using the doctor blade technique. The electrical performance of the TENG is assessed by connecting a capacitor or various load resistors to the circuit. 3 wt% GnPs@PVDF/PEEK & Nylon 6.6 nanofibers and 3 wt% GnPs@PVDF/PEEK & PEO/Glass veil TENGs deliver output voltages of 470 V and 303 V, respectively at 75.8 MΩ load resistance. The power densities of 3 wt% GnPs@PVDF/PEEK & Nylon 6.6 nanofibers and 3 wt% GnPs@PVDF/PEEK & PEO/Glass veil TENGs at 1.1 MΩ are 7.36 W/m² and 4.04 W/m², respectively. Root mean square (R_RMS), peak to peak height (R_pp), and arithmetic mean height (R_a) of the surface roughness of 3 wt% GnPs@PVDF/PEEK are measured to be 17.59 µm, 151.08 µm, and 13.16 µm, respectively. Parallel to increased surface roughness, the output power, and output voltage of 3 wt% GnPs@PVDF/PEEK & PEO/Glass veil TENG increase by 4 and 2.23-fold, respectively. Further GnPs embedding reduces both surface roughness and electrical performance of the TENG. I believe that GnPs@PVDF/PEEK veil material has the potential to be used to make high-performance TENGs that can power portable, wearable, and self-powered electronics.

摩擦纳米发电机 (TENG) 是最先进的设备，它通过摩擦起电和静电感应的耦合效应通过收集机械能来发电。本研究旨在通过采用基于 GnPs 的简单且廉价的方法来提高 TENG 的电气性能，该 TENG 可收集生物力学能量为可穿戴和便携式电子设备供电。为此，我设计并生产了一种垂直接触分离模式 TENG，适用于使用摩擦负材料聚偏二氟乙烯 (PVDF)/聚醚醚酮 (PEEK) 面纱和摩擦正材料聚环氧乙烷 (PEO)/玻璃和尼龙 6.6 纳米纤维进行生物力学能量收集. 使用刮刀技术，PEEK 面纱的表面涂有具有优异摩擦负性和铁电极化特性的 PVDF 溶液。通过将电容器或各种负载电阻器连接到电路来评估 TENG 的电气性能。3 wt% GnPs@PVDF/PEEK & Nylon 6.6 纳米纤维和 3 wt% GnPs@PVDF/PEEK & PEO/Glass veil TENG 在 75.8 MΩ 负载电阻下分别提供 470 V 和 303 V 的输出电压。3 wt% GnPs@PVDF/PEEK & Nylon 6.6 纳米纤维和 3 wt% GnPs@PVDF/PEEK & PEO/Glass veil TENGs 在 1.1 MΩ 的功率密度为 7.36 W/m PEO/Glass veil TENG 在 75.8 MΩ 负载电阻下分别提供 470 V 和 303 V 的输出电压。3 wt% GnPs@PVDF/PEEK & Nylon 6.6 纳米纤维和 3 wt% GnPs@PVDF/PEEK & PEO/Glass veil TENGs 在 1.1 MΩ 的功率密度为 7.36 W/m PEO/Glass veil TENG 在 75.8 MΩ 负载电阻下分别提供 470 V 和 303 V 的输出电压。3 wt% GnPs@PVDF/PEEK & Nylon 6.6 纳米纤维和 3 wt% GnPs@PVDF/PEEK & PEO/Glass veil TENGs 在 1.1 MΩ 的功率密度为 7.36 W/m²和 4.04 W/m ²，分别。3 wt% GnPs@PVDF/PEEK 的表面粗糙度的均方根( R _RMS )、峰峰高度 ( R _pp ) 和算术平均高度 ( R _a ) 分别为 17.59 µm、151.08 µm 和 13.16微米，分别。在增加表面粗糙度的同时，3 wt% GnPs@PVDF/PEEK 和 PEO/Glass veil TENG 的输出功率和输出电压分别增加了 4 倍和 2.23 倍。进一步嵌入 GnPs 会降低 TENG 的表面粗糙度和电气性能。我相信 GnPs@PVDF/PEEK 面纱材料具有制造高性能 TENG 的潜力，可以为便携式、可穿戴和自供电电子设备供电。
