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.

用于电场能量收集的摩擦纳米发电机的评估

电场能量采集器 (EFEH) 已成为利用带电环境周围电场的一项有前途的技术。目前的研究表明，EFEH 与摩擦纳米发电机 (TENG) 密切相关。然而，TENG 在通电环境中的性能仍不清楚。这项工作旨在评估 TENG 在电场能量收集应用中的性能。为此，对以单电极模式运行的不同尺寸的 TENG 进行了概念化、组装和实验测试。每个 TENG 安装在 1.5 HP 单相感应电机上，在 8 A、230 V 和 50 Hz 的标称参数下运行。此外，接触层安装在线性电机上以控制运动刺激。 TENG 成功地感应了电场，并在变化较大的电场中提供了令人满意的静电电荷收集性能。实验结果表明，与简单的 EFEH 相比，使用 TENG 的能量收集量大约增加了 1.51% 至 10.49%。观察到的功率密度和电场之间的相关性凸显了 TENG 在电气化环境中比 EFEH 更有效的能源，从而有助于作者正在进行的研究目标。
