With the rapid development of advanced materials and manufacturing technologies, flow sensors have made significant progress in the field of mechanical engineering, which could cater to the development trend of the Internet of Things (IoT) and the ongoing Fourth Industrial Revolution. However, traditional power supply modes such as lithium batteries require regular recharging or replacement, which greatly causes too much inconvenience and maintenance consumption, and may also pose potential risks to the marine environment. The triboelectric nanogenerators (TENGs), based on the coupling effect of contact electrification and electrostatic induction, have been demonstrated to convert mechanical movements of the fluid into electrical signals with various features such as flexibility, conformability, and user‐friendliness. This review systematically summarizes for the first time the fundamental working mechanism, rational structural design, and analysis of practical application scenarios of triboelectric flow sensor as an emerging technology for flow monitoring of the Industrial IoT. According to the different fluid objects monitored, the latest representative achievements of triboelectric flow sensors can be divided into gas flow sensors, liquid flow sensors, and two‐phase flow sensors. Finally, the current challenges and future development directions of triboelectric flow sensors are examined, which can promote the further development of the field of the flow sensors.

“…Recent studies show that contact electrification occurs not only at a solid–solid interface, 4–6 but also at liquid–solid 7,8 and liquid–liquid interfaces. 9,10 Although applications based on contact electrification in energy, 11–13 physics 14 and surface chemistry, 15–18 such as triboelectric nanogenerators, have been widely studied, the exact mechanism of the triboelectric effect is still controversial and unclear. 19,20 How the charges are transferred between the two contacting materials, whether this involves electrons 21–24 or adsorbed ions, 25 is still debated, especially for liquid–solid cases.…”

Protecting marine environment is an important and urgent task to maintain marine ecological balance. As a promising blue energy harvesting technology, triboelectric nanogenerator (TENG) can provide electrical energy for marine environmental protection. Previous reported swing‐structured TENGs have advantages of low driving force in low‐frequency water waves and strong durability, but the space utilization and volume power density are relatively low. Here, a multilayered swing‐structured TENG (MS‐TENG) with low wear is designed to increase the space utilization rate, and thereby enhance the output performance. The MS‐TENG generates the highest peak power density of 15.18 W m−3 Hz−1 and average power density of 3.56 W m−3 Hz−1 under water wave triggering at 0.8 Hz. By coupling the charge pumping and non‐contact mode of main TENGs, the MS‐TENG achieves strong performance stability, exhibiting little attenuation of electric output after 240 000 cycles. Furthermore, the MS‐TENG has successfully powered a water quality detector for self‐powered ballast water quality monitoring, and an application is presented about electrical dehydration of water‐in‐oil emulsions driven by the MS‐TENG with a dehydration rate of 99.6%. This work promotes the development of high power density MS‐TENG and demonstrates its application potential for self‐powered marine environmental protection.
