Boosting the Power Output of a Cement-Based Triboelectric Nanogenerator by Enhancing Dielectric Polarization with Highly Dispersed Carbon Black Nanoparticles toward Large-Scale Energy Harvesting from Human Footsteps

“…Compared to other cement-based TENGs that employed cement composites as tribopositive materials, the power density of the cement-CB in the present work was almost 10 times greater than that of the cement-TiO 2 TENG and comparable to the calcium silicate (cement), natural rubber composite TENG (2.46 W/m 2 ) . In addition, the output power of the fabricated TENG with the cement tribopositive material in this study was higher than that of the cement-based conductive composite TENG (5.1 μW/cm 2 ) where conductive cement was employed as a conductive element in the TENG …”

“…It was noticed that the maximum power in this work was obtained at relatively low matched load resistance compared to many previously reported TENGs. , The matched load resistances, voltage, and current measured at matched load and power densities of some previously reported TENGs are listed in Table S3 compared to those of our cement-CB TENG in this work. Low matched load resistance of cement-CB TENG suggested that adding conductive CB resulted in the reduction of internal resistance of the cement material.…”

“…Low internal resistance promoted charge transfer, giving rise to the high power output of TENG . This was evidenced by the superior output current at a matched load of the cement-CB TENG (69 μA), which was higher than those of the cement-TiO 2 TENG (9 μA) and the cement-based conductive composite TENG (0.8 μA) as well as those of the previously reported TENGs (Table S3). This indicated that charge transfer was improved significantly in the cement-CB composite TENG.…”

Multiscale Engineering of Sustainable and Versatile All‐Fiber Triboelectric Nanogenerator Based on Multifunctional Fibrous Materials and 3D Woven Architecture

“…In this study, output voltage is measured by the device (oscilloscope) which is based on the measurement of flowing current through oscilloscope. [ 58 ] Therefore, the output voltage increases from 8.24 to 27.33 V when the impacting frequency varies from 1 to 3 Hz.…”

Nanocrystalline triple perovskite compounds A3Fe2BO9(A = Sr, Ba; B = W, Te) with ferromagnetic and dielectric properties for triboelectric energy harvesting

“…TENGs work on the principle of triboelectrification and electrostatic induction. 53 TENGs are capable of converting mechanical energy into electrical energy as two triboelectric layers come into contact with each other having differences in work function or surface charge polarity. The conventional triboelectric series mainly highlights the presence of metals and polymers.…”
