Electric-field energy harvesters (EFEHs) have emerged as a promising technology for harnessing the electric field surrounding energized environments. Current research indicates that EFEHs are closely associated with Tribo-Electric Nano-Generators (TENGs). However, the performance of TENGs in energized environments remains unclear. This work aims to evaluate the performance of TENGs in electric-field energy harvesting applications. For this purpose, TENGs of different sizes, operating in single-electrode mode were conceptualized, assembled, and experimentally tested. Each TENG was mounted on a 1.5 HP single-phase induction motor, operating at nominal parameters of 8 A, 230 V, and 50 Hz. In addition, the contact layer was mounted on a linear motor to control kinematic stimuli. The TENGs successfully induced electric fields and provided satisfactory performance to collect electrostatic charges in fairly variable electric fields. Experimental findings disclosed an approximate increase in energy collection ranging from 1.51% to 10.49% when utilizing TENGs compared to simple EFEHs. The observed correlation between power density and electric field highlights TENGs as a more efficient energy source in electrified environments compared to EFEHs, thereby contributing to the ongoing research objectives of the authors.
电场能量采集器（EFEH）已成为一种利用通电环境周围电场的有前途的技术。目前的研究表明，EFEH与摩擦电纳米发电机（TENG）密切相关。然而，TENG在通电环境中的性能仍不明确。这项工作旨在评估TENG在电场能量采集应用中的性能。为此，构思、组装并对以单电极模式运行的不同尺寸的TENG进行了实验测试。每个TENG都安装在一台1.5马力的单相感应电动机上，该电动机在8A、230V和50Hz的标称参数下运行。此外，接触层安装在直线电机上以控制运动刺激。TENG成功地感应出电场，并在相当可变的电场中提供了令人满意的性能来收集静电荷。实验结果表明，与简单的EFEH相比，使用TENG时能量收集量大约增加了1.51%至10.49%。观察到的功率密度与电场之间的相关性突出了TENG在通电环境中是比EFEH更高效的能源，从而有助于作者正在进行的研究目标。
