“…Therefore, the matching load resistance ( R L ) decreases in terms of the balanced frequency ( w = 1/R L C total ), thus RMS current is increased. [ 46 ] Due to the trade‐off between these two opposing tendencies, the output increases with permittivity until it reaches an optimal value, beyond which it starts to decrease.…”

Reducing the impedance of a triboelectric nanogenerator (TENG) without power loss is crucial for enhancing its energy conversion efficiency and overall performance. In this paper, a novel signal management structure, based on a newly designed sliding‐mode TENG, aimed at effectively reducing impedance by converting narrow, instantaneous signals into broader ones is presented. This transformation is accomplished by adding a grounded electrode connected to a high‐inductive inductor and fine‐tuning the parasitic capacitance of the dielectric material. Utilizing a highly resistive material like P(VDF–TrFE), a significant improvement in the TENG's performance is achieved, resulting in an increase of output power to 0.352 mW and a decrease in impedance from 3.2 to 0.3 MΩ. This results in a threefold increase in charging speed, which can be attributed to the reduced charge loss and improved matching at lower impedance. Based on these promising findings, the enhanced TENG is successfully connected to power a system for electrochemical CO2 reduction for CO production. This system effectively reduces the required electrochemical reduction potential by ≈15% under real environments.

“…The capacitance of the TENG can be represented as [ 38 ]

C false(t false) = \frac{ε_{0} A}{\frac{d}{ε_{normalr}} + x false(t false)}

where x (t) is the relative displacement between two electrodes,

ε_{normalr}

is the relative dielectric constant, A is the electrode surface area, and d is the thickness of the dielectric layer. Although there may be a deduction in the effective dielectric constant if atmospheric air fills the interfacial gap between the copper electrode and FEP, the effective capacitance improved due to the increase in the surface area of the electrode.…”

Triboelectric nanogenerators (TENGs) are promising cost‐effective energy harvesters useful to scavenge vibration or mechanical movements from various domains. Ranging from condition monitoring of machines to motion sensing of humans, its applications are enormous in the internet of things scenario. Enhancing the performance of small‐sized TENGs is of great demand, and pulsed laser‐assisted texturing is an efficient and proven method to enhance the output of energy harvesters. This work studies simultaneous laser patterning of fluorinated ethylene propylene (FEP) dielectric material and the underneath copper electrode with three different wavelengths (355, 532, and 1064 nm) of the Nd3+:YAG laser and the device's electrical performance is analyzed. The maximum enhancement is observed in the case of 355 nm laser‐assisted patterning on FEP and Cu electrode with a laser fluence of 10 J cm−2. The improvement is least in the case of 1064 nm laser‐assisted patterning. Laser patterning on the underlying electrode with this new approach is able to produce an enhancement in the TENG output. However, patterning on the FEP top surface is critical in the process.

“…Capacitance denotes the capacity of the TENG device to retain electrical charge [44,45]. Consequently, the conversion efficacy can be improved by increasing the charge density [46,47]. Tribo-pairs are the primary component of all TENG devices; they have a direct impact on the TENG's output performance via the surface charge density characteristic [48].…”

The field of transportation plays a crucial role in the development of society. It is vital to establish a smart transportation system (STS) to increase the convenience and security of human life. The incorporation of artificial intelligence (AI) and the Internet of Things (IoT) into the traffic system has facilitated the emergence of innovative technologies like autonomous vehicles or unmanned aerial vehicles (UAVs), which contribute to the reduction of traffic accidents and the liberation of human driving time. However, this improvement involves the use of multiple sensor devices that need external power sources. As a result, pollution occurs, as do increases in manufacturing costs. Therefore, the quest to develop sustainable energy remains a formidable obstacle. Triboelectric nanogenerators (TENG) have emerged as a possible solution for addressing this problem owing to their exceptional performance and simple design. This article explores the use of TENG-based self-power sensors and their potential applications in the field of transportation. Furthermore, the data collected for this study might aid readers in enhancing their comprehension of the benefits linked to the use of these technologies to promote their creative ability.
