With the intrinsic characters of high voltage and low current, triboelectric nanogenerators (TENGs) serving as green high voltage (HV) power source exhibit excellent practicability and safety compared to traditional HV power sources. To further simplify the TENG-based HV power source system, a single electrode mode TENG (SE-TENG) with simple wiring is first employed to generate ultra-high voltage power in this work. By optimizing surface charge density and the thickness of packing layer between the primary electrode and reference electrode, a record value of 12.7 kV is achieved for SE-TENGs. Furthermore, a calculation method based on a capacitance model is proposed to accurately measure the open voltage of TENG with a wide range (over 10 kV). The SE-TENG-based HV power source is successfully applied to power electronics and generates negative air ions for air cleaning. This work significantly simplifies TENG-based HV power sources, and is expected to enrich the diversity of high-voltage applications based on the reach of existing technologies.

实现超高压 (≈10 kV) 摩擦纳米发电机

摩擦纳米发电机（TENGs）具有高电压和低电流的固有特性，作为绿色高压（HV）电源，与传统高压电源相比具有优异的实用性和安全性。为了进一步简化基于 TENG 的高压电源系统，本工作首先采用布线简单的单电极模式 TENG (SE-TENG) 来产生超高压电源。通过优化表面电荷密度和主电极与参比电极之间填充层的厚度，SE-TENGs 达到了 12.7 kV 的记录值。此外，还提出了一种基于电容模型的计算方法，以准确测量宽范围（超过 10 kV）的 TENG 开路电压。基于SE-TENG的高压电源成功应用于电力电子，产生空气负离子净化空气。这项工作显着简化了基于 TENG 的高压电源，并有望在现有技术的基础上丰富高压应用的多样性。
