As an effective high-voltage supply, triboelectric nanogenerator (TENG) shows the output characteristics of high voltage (~kV) and low current (~µA) with advantages of low cost, high safety and high portability. Usually, the serious material abrasion and voltage output lower than 10 kV of TENG have limited its practical high-voltage application. Herein, a polyester fur-reinforced rotary triboelectric nanogenerator (PFR-TENG) with an ultra-stability high voltage output is proposed. Based on the appropriate work function and electronegativity, a soft polyester fur layer, as the charge pump and charge transmitter, is introduced to form partial soft-contact and non-contact. Therefore, PFR-TENG maintains 100% electrical output after 100k cycles. Adopting ternary dielectric triboelectrification design, 15 kV DC voltage and 10 kV AC voltage are obtained easily without a voltage-multiplying circuit. To prove the practicability of the TENG, the high-voltage pulsed electric field generated by PFR-TENG is used to promote seed germination. The germination index and vigor index increase by 34.4% and 351.2% compared with untreated seeds. This work shows a feasible strategy for improving the stability and voltage output of the TENG, and expands the application of TENG as high-voltage equipment for high-tech agriculture.

作为一种有效的高压电源，摩擦纳米发电机（TENG）显示出高电压（~kV）和低电流（~μA）的输出特性，具有低成本、高安全性和高便携性的优势。通常，TENG严重的材料磨损和低于10 kV的电压输出限制了其实际的高压应用。在此，提出了一种具有超稳定高压输出的聚酯毛皮增强旋转摩擦纳米发电机（PFR-TENG）。基于适当的功函数和电负性，引入柔软的聚酯皮层作为电荷泵和电荷发射器，形成部分软接触和非接触。因此，PFR-TENG 在 10 万次循环后保持 100% 的电输出。采用三元介质摩擦起电设计，无需倍压电路即可轻松获得15 kV直流电压和10 kV交流电压。为了证明TENG的实用性，PFR-TENG产生的高压脉冲电场用于促进种子萌发。与未经处理的种子相比，发芽指数和活力指数分别提高了34.4%和351.2%。该工作为提高TENG的稳定性和电压输出提供了一种可行的策略，并扩展了TENG作为高科技农业高压设备的应用。
