“…For instance, triboelectric nanogenerator (TENG) technology represents a significant advance in converting various mechanical energy taken from the environment into electrical energy. [82,83] Similarly, a piezoelectric nanogenerator generates electricity through the piezoelectric effect. It operates on the principle that when mechanical stress is applied to materials (such as bending, stretching, or any form of deformation), they generate an electric charge in response to the stress, thereby producing electrical energy.…”

Although batteries are a highly popular energy source in biosensors, batteries can be an economic limitation for low‐cost sensing applications and pose significant challenges in miniaturization, biocompatibility, and disposal. To surmount such issues, “self‐powered sensors” gain the spotlight thanks to their energy harvesting from the environment through embedded miniaturized systems. In this review, the recent developments in self‐powered devices are summarized with a specific focus on the integration of supercapacitors with sensors and biosensors. The working principles of microsupercapacitors, fabrication methods, their integration with biosensors, and their ultimate applications (i.e., biomedical monitoring and analytical biomarker detection) are described. Different energy harvesting systems are summarized and their integration with self‐powered sensors or biosensors is highlighted. The limitations and challenges of the existing approaches and the future of supercapacitor‐integrated sensing systems are also critically discussed.

“…[28][29][30] As such, it is critical to alleviate the triboelectric layer abrasion and enhance the efficiency and lifespan of solid-solid TENGs by employing supplementary techniques. [31][32][33][34][35] Moreover, solid-solid TENGs lack environmental adaptability and are susceptible to variations in weather conditions and surrounding humidity. To address these issues, researchers have directed their attention to developing liquid-solid TENGs as an alternative to solid-solid TENGs.…”

As the increasing scarcity of fossil fuels and the ever‐present need to address environmental concerns are faced, the development of efficient and sustainable energy harvesting techniques gains more and more significance. The liquid–solid triboelectric nanogenerator (TENG) has emerged as a promising solution for harvesting mechanical energy in water. Although the liquid–solid contact electrification technique is studied by numerous researchers, there is still a need to enhance energy harvesting efficiency in liquid–solid TENG. This comprehensive review discusses recent advances in kinetic energy harvesting from water, focusing on the solid–solid and liquid–solid interaction mechanisms when using TENGs as an energy conversion medium. The review summarizes the recent developments in structure design and material improvements, as well as hybridization with other generators as methods of enhancing the output performance of TENG. Besides discussing advancements of TENG, the potential impact and future challenges of liquid–solid TENG are highlighted. This paper provides insight into the current state of knowledge and the future directions of research in the field of liquid–solid TENG energy harvesting.

“…If the initial conditions of the system, such as resistance and speed, change, and the output signals will undergo distortion [4][5][6], then the steady-state of the triboelectric nanogenerator system will inevitably also undergo changes. The output signals research of the triboelectric nanogenerator system often uses static physical models [7,8] for simulation, which can easily calculate the spatial characteristics of potential, electric field, and charge distribution, but is not sufficient to analyze dynamic situations. Recently, the dynamic physical models of the triboelectric nanogenerator system have begun to receive attention, used to simulate dynamic situations such as potential differences and charge transfer over time, and thus reveal the nonlinear dynamic behavior of the triboelectric nanogenerator system.…”

As a nonlinear dynamic system, the dynamic equation of triboelectric nanogenerator system is not only difficult to accurately establish, but also difficult to solve. The output signals of triboelectric nanogenerator system depends on the initial conditions of the system, which reflects the dynamic behavior of the system. Currently, there is little research on using the output signals to study the dynamic behavior of triboelectric nanogenerator system. Therefore, a dynamic simulation model of a freestanding triboelectric nanogenerator (F-TENG) system was established using COMSOL software. The mathematical model of the F-TENG system was fitted. Using chaos theory and its phase-space reconstruction technology, the phase-space trajectories of the F-TENG system were reconstructed through voltage signals under external factors, and the dynamic behavior of the F-TENG system was discussed and studied. Finally, validation experiments were carried out. The research shows that with the variation of internal factors and operating frequency, the mathematical model of the F-TENG system remains basically unchanged, and the variation law of output characteristics also remains basically unchanged. The F-TENG system is in periodic motion; With the variation of external factors such as resistance and friction layer spacing, the mathematical model of the F-TENG system will evolve in a complex direction, and the output characteristics will gradually distort. The F-TENG system will evolve from periodic motion to chaotic motion. The research results not only reveal the dynamic behavior and enrich the nonlinear dynamic theory of triboelectric nanogenerator system, but also provide theoretical guidance for increasing the working bandwidth and stability of triboelectric nanogenerator system.
