With the increasing demand for carbon neutrality, the development of renewable and recycle green energy has attracted wide attention from researchers. A novel self-healing triboelectric nanogenerator (TENG) was constructed by applying a linear silicone-modified polyurethane (PU) coating as a triboelectric layer, which was obtained by reacting hydroxypropyl silicone oil and hexamethylene diisocyanate under the catalysis of Sn. The linear self-healing coating as the friction electrode could effectively alleviate the damages of TENG devices during long-term energy harvesting. When the triboelectric layer of the TENG device shows abrasion, the broken silicone-modified polyurethane polymer chains would gradually be cross-linked again through hydrogen bonding to achieve a self-healing effect. The entire self-healing process of the friction coating could be completed in 30 min at room temperature. The PU-based self-healing TENG exhibits an evident and stable output performance with a short-circuit current of 31.9 μA and output voltage of 517.5 V after multiple cutting–healing cycles, which could light 480 commercial LEDs. Besides, a self-powered cathodic protection system supplied by the self-healing TENG was constructed, which could transfer negative triboelectric charges to the protected metal surface to achieve an anti-corrosion effect by harvesting mechanical energy. Due to the self-healing characteristics of the TENG device as the power supply part, this intelligent system possesses great application potential in the long-term corrosion protection of multiple metal application industries, such as the marine industry.

Various sensors are indispensable for the rapid development of modern engineering and play an important role in human economic development and social progress. The number of these sensors is enormous and widely distributed, it is impractical to use only batteries to drive the entire sensor network. The use of batteries will also bring difficulties in tracking and recycling and possible environmental pollution and health hazards. Consequently, developing selfpowered sensor technologies capable of self-driving operation utilizing ambient energy is highly desirable and necessary.In 2012, Wang's group first invented triboelectric nanogenerators (TENGs), [1,2] its great potential in self-powered systems has attracted widespread attention from researchers. [3,4] The basic working principle of TENGs can be explained by the coupling effect of contact electrification and electrostatic induction effect, [5][6][7] which can convert the energy of the surrounding environment into electrical energy, and has the advantages of simple structure, convenient implementation, diverse material selectivity, and wide application. [8,9] It is considered the most promising alternative to traditional battery technology. [10] As one of the most important and abundant renewable energy sources in natural activities, [11][12][13] fluid energy mainly includes wind energy, airflow energy, droplet energy, water flow energy, and wave energy. Hence, the use of TENGs to harvest these fluid energies for clean, distributed, and self-powered sensing technology is a good option. [14,15] Figure 1 summarizes the typical examples and application scenarios of triboelectric fluid sensors (TFSs) under different fluid energy states in recent years.In this paper, the research status of TFSs is reviewed. First, the basic theory and working modes of TFSs are reviewed, including gas-based and liquid-based. Then, the research progress of gas-based triboelectric sensors, liquid-based triboelectric sensors, and multiphase flow-based triboelectric sensors is introduced, respectively. Many researchers have developed and implemented TFSs designs for different functions, including wind speed, flow, concentration, liquid level, position, motion, etc. In addition, the main applications of TFSs in the fields of natural environment monitoring, industrial pipeline monitoring, urban air purification, industrial wastewater treatment, Fluid energy is one of the most common, widely distributed, and significant renewable energy sources globally, which generally exists in gases and liquids such as wind energy, airflow energy, droplet energy, water flow energy, and wave energy. Since Wang's research group first invented the triboelectric nanogenerators (TENGs) in 2012, it has been widely utilized and developed rapidly as a new energy conversion method and as a promising sensing technology. Especially in fluid sensing, the TENGs get a lot of attention. This paper comprehensively reviews the latest research on triboelectric fluid sensors (TFSs). First, the fundamental theories and bas...

The condition monitoring of piston–cylinder‐reciprocating machinery usually relies on vibration and acoustic sensors installed on the outer surface of cylinders. However, vibration and acoustic signals are susceptible to external interference from other accessories, and require an external power supply, which limits its widespread application. Herein, based on the lateral sliding mode of triboelectric nanogenerator (TENG), a novel reciprocating device with condition‐monitoring and self‐powering capabilities is proposed, called piston–cylinder triboelectric nanogenerator (PCTN). The effects of different factors, including mean piston speed, number of piston rings, materials of piston ring and cylinder, on the output characteristics of PCTN are investigated, respectively. Two typical fault cases, that is, piston ring missing and coil fracture, are investigated to verify the condition‐monitoring capability of PCTN. Piston ring missing faults can be effectively identified based on the variations in peak and root‐mean‐square (RMS) values of short‐circuit current (I sc). Coil fracture faults can be identified and located by analyzing changes in time–domain curve and time–‐frequency spectrum of I sc. Herein, a theoretical and experimental basis for the widespread application of PCTN in reciprocating machinery is provided.
