“…Wang et al developed a solid-liquid-solid TENG comprising a hydrophilic graphite electrode, as shown in Figure 12b. [138] Compared to the hydrophobic graphite electrode, the hydrophilic graphite electrode can make the water contact with the electrode more fully, increasing the output by the EDL between water and electrode. In addition, this TENG is capable of harvesting energy over long distances and maintaining stable output performance at distances ranging from 0.2 to 1.6 m. The wave energy availability in the environment is not constant but appears randomly, making it difficult to harvest.…”

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.

“…One example of this is a solid-liquid-solid mode TENG developed by Wang et al, which utilizes a device consisting of PTFE, water, and graphite to detect the amplitude and frequency of human fingers. 113 The water in the device not only serves as a triboelectric material but also transmits energy and signals, while the modified graphite electrode enhances the output of TENG. By tapping a finger on the PTFE sheet, this device can convert the output voltage into the international Morse code using spikes and flat band signals.…”

Self-powered sensors have emerged as a promising solution to this challenge, offering a range of benefits such as low cost, high stability, and environmental friendliness. One of the most promising self-powered sensor technologies is L-S TENG, which stands for the liquid-solid triboelectric nanogenerator. In this review paper, the working principle with three basic modes has been briefly introduced firstly. After that, affecting parameters to L-S TENG are reviewed based on the properties of the liquid and solid phases. With different working principles, L-S TENG has designed a lot of structure that works as self-powered sensor for pressure/force change, liquid flow motion, concentration, and chemical detection or biochemical sensing. On the other hand, the continuous output signal of TENG plays an important role in a real-time sensor which is extremely necessary for the development of the Internet of Things.

COVID-19 broke out all over the world, and the medical protective mask is an important epidemic prevention equipment. Traditional medical protective masks use electret polypropylene melt-blown cloth as the core filter material. However, it relies heavily on electrostatic filtration and has high filtration resistance. The one-time electret makes the static charge decay rapidly with the water vapor generated by breathing, which affects the service life of the mask. In this paper, PTFE/PVA fiber and PVDF fiber were fabricated by conjugate electrospinning method, and the PTFE/PVA-PVDF layer blending fluffy fiber membrane was obtained by on-line mixing. Under the action of air slip effect and triboelectric secondary electret, the fiber membrane has higher filtration efficiency, lower filtration resistance and longer service life. The initial filtration efficiency of the fiber membrane is above 95%, the filtration efficiency is near to 100% after 24 times of cyclic filtration, the filtration resistance is about 110 Pa, the air permeability of the fiber membrane is 262.88–370.70 mm/s, and the moisture permeability is as high as 7721–8471 g/ (m 2 ·24 h).
