“…Generally, a higher rotational speed has a bigger impact on the voltage output and results in better performance compared to a lower rotational speed. This materializes as a higher rpm leads to an increase in friction between two surfaces made of triboelectric material, resulting in heat and higher charge generation in the system [22]. As stated earlier, higher rotational speeds result in higher voltage generation, which can serve as the foundation for further studies on extremely high rpm values.…”

“…The Royal Society of Chemistry reported in research from 2021 that the TEG can effectively recycle spinning mechanical energy to power various electrical devices at an impressively high rotational speed of 7500 rpm [22]. In this experiment, substantially lower rotational speeds were tested, ranging from 500 to 1500 rpm, to see if TEG could still provide adequate power.…”

Triboelectric generatorshave the ability to harvest energy from human activities, mechanical vibration, and other sources to drive minor electronic devices.In many circumstances, charges created from a triboelectric process are referred to as a negative effect or waste energy. Here, this paper will demonstrate an approach of the charging process in friction with a rotator and stator to investigate the effects of rotating speed and the different thickness of electrification to the output voltage. The 360° lateral sliding disc triboelectric generator (TEG) fabricated by connecting an Aluminium disc to the motor as a rotator, while a Polyvinyl Chloride (PVC) sheet placed at the top of an acrylic coated by a copper electrode served as a stator. PVC material with different thicknesses (0.2, 0.5 and 0.7 mm) and grit sizes were used (P500, P1000 and P1500) and prepared prior to the experiment. Thus, three different rotational speeds (500, 1000 and 1500 rpm) were monitored using a tachometer to standardize the speed for each set of experiment. Such as a TEG at 1500 rpm on a 0.2 mm thick sample with P500 grit size modification delivers a maximum voltage output, VRMSof 13.8 mV, with the maximum calculated current of 69 µA and the maximum power density of 0.485 mW/m2.

“…The researchers have demonstrated the numerous applicability of the nanogenerator, generating greater interest in the battery-free technology as well as implantable and wearable technology by the biomechanical energy harvesting and sensing systems. [70,71,72,73] Here, we have studied the applicability of the proposed chitin-based triboelectric and piezoelectric nanogenerators by simple biomechanical systems. To begin the selfpowered implementation of the BSF biofilm-based TENG, we have utilized an energy storage system to operate a calculator (1 μF capacitor) via a bridge rectifier, as shown in Figure 4a (The operating movie is demonstrated in Supplementary Movie S1).…”

With the increasing demand for portable electronic devices and the shortage of conventional energy resources, energy harvesting from natural resources has gained much attention. Herein, they proposed a black soldier fly (BSF) derived chitin biofilm to fabricate high‐performance triboelectric and piezoelectric nanogenerators. The physiochemical characterizations of the chitin biofilm are demonstrated by the presence of the hydroxyl group, alpha chitin, and beta chitin, which are responsible for the remarkable tribopositive, and piezoelectric function of the chitin derived from BSF. The electrical performance of the proposed work, such as voltage, current, and instantaneous power from BSF/PTFE‐based triboelectric nanogenerator (TENG) are exhibited at 121 V, 15 µA, and 217.8 µW, respectively. Ag/BSF/Ag piezoelectric nanogenerator (PENG) is generated 18 V voltage, 2.2 µA current, and 5 µW instantaneous power. Moreover, the proposed TENG and PENG devices demonstrate the ability to charge the dielectric capacitors and drive low‐power electronic devices like LEDs and a calculator. The proposed results suggested that chitin is a superior biomaterial for developing sustainable energy harvesting devices.

“…Additionally, the human body itself provides a valuable source of mechanical energy and chemical targets, making it an attractive option for detecting substances from the human body by recycling the mechanical energy of human movement. In the second class, TENG is directly used for chemical sensing with a functional material serving as the contact interface. − As the material reacts with different levels of monitoring chemicals, its electronegativity changes and the triboelectric output is altered, allowing for sensing capabilities. , This system is termed the TENG-based self-powered active chemical sensing system, which simplifies the overall structure and expands the potential uses for self-powered chemical sensors. Although TENG-based self-powered chemical sensors could perform quantitative analysis of the target chemicals, it is difficult to achieve qualitative detection because the surface of tribo-materials often does not have specificity for target molecules.…”

With the popularization of the Internet of Things, the application of chemical sensors has become more and more extensive. However, it is difficult for a single functional sensor to meet multiple needs at the same time. For the next generation of chemical sensors, in addition to rapid qualitative and quantitative detection, it is also necessary to solve the problem of a distributed sensor power supply. Triboelectric nanogenerator (TENG) and surface-enhanced Raman scattering (SERS) are two emerging technologies that can be used for chemical testing. The combination of TENG and SERS technology is proposed to be an attractive research strategy to implement qualitative and quantitative analysis, as well as self-powered detection in one device. Herein, the Ag nanoparticle (NP)@polydimethylsiloxane (PDMS) plasmonic cavity is demonstrated, which can be exploited not only as a SERS substrate for qualitative analysis of the target molecules but also as a TENG based self-powered chemical sensor for rapid quantitative analysis. More importantly, the as-designed plasmonic cavity enables prolonged triboelectric field generated by the phenomena of triboelectricity, which in turn enhances the “hot spot” intensities from Ag NPs in the cavity and boosts the SERS signals. In this way, the device can have good feasibility and versatility for chemical detection. Specifically, the measurement of the concentration of many analytes can be successfully realized, including ions and small molecules. The results verify that the proposed sensor system has the potential for self-powered chemical sensors for environmental monitoring and analytical chemistry.
