“…The experimental results are shown in Figure 5 f. The most relevant findings from this experiment are the following: (i) the proposed harvester can collect enough energy to drive low-power electronics; (ii) the output voltage increases in accordance with the value of the storage capacitor; (iii) the selection of the capacitor directly influences the available and collected energy. Such findings reinforce the early conclusions shown in [ 39 ].…”

“…As shown in Figure 7 , the observed lower power density of the TENG mode compared to the EFEH mode can be attributed to the utilization of low-cost materials (PLA and CA) in the construction of the harvester. Present efforts are directed toward fabricating TENGs using advanced biocompatible and eco-friendly materials [ 2 , 39 , 46 ]. Many of these studies have primarily focused on substituting dielectric and metal layers with advanced materials such as aerogels or bioplastics [ 47 , 48 ], highlighting how the robustness and durability of the TENG is able to change the performance of the TENGs.…”

“…Displacement current-based harvesters face two significant constraints: (i) low-power density and (ii) high capacitive impedance [ 1 , 38 ]. To address these challenges, the assumptions made in [ 6 , 28 , 39 ] were adopted, where the authors introduced rectification and storage stages as prerequisites for the proper operation of the energy harvester. According to [ 29 , 40 ], the power density of harvested energy is higher when employing full-wave rectifiers compared to half-wave rectifiers in the electric-field energy harvesting process.…”

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.
