“…More importantly, water–solid triboelectrification is insensitive to environment humidity, which provides a wide possibility to design stable water-energy-based harvesters and sensors. Until now, several water–solid TENGs have been developed for water-energy harvesting from rain, − water flow, − and ocean waves. − However, most water–solid TENGs suffer from low triboelectrification current and low output power, thereby limiting their potential in broader applications.…”

“…The critical point to enhance the output performance of water–solid TENG is to increase the surface charge density. A lot of effort has been made to overcome this obstacle, including the design of new materials, surface modification, micro/nanostructure optimization, and ion implantation, all of which are also widely used in solid–solid TENGs. Most of these processes are complex, expensive, non-large-area preparation, and time-consuming.…”

Water−solid triboelectric nanogenerators (TENGs) are insensitive to ambient humidity, providing a wide range of possibilities for designing stable waterenergy-based harvesters and self-powered sensors. However, the wide application of most water−solid TENGs has been limited by low triboelectrification performance. To boost the output performance of water−solid TENGs, a newly structured TENG has been developed by adding a polyimide (PI) as a charge storage intermediate layer between the friction layer and the conducting layer, significantly improving the output performance (1.260 mW), with a 5-fold increase compared to the water−solid TENG without the PI intermediate layer (0.234 mW). This analysis shows that adding an intermediate layer with a high density of electron capture sites to the TENG results in more triboelectric charge being retained, thereby improving the electrical performance of TENG. The electrical performance of TENG is related to the thickness of the PI layer, but this is not a positive correlation. Contact angles and falling heights between the droplet and the device also affect the output performance. Finally, the water−solid PI-TENG we have developed has promise in hydropower harvesting capabilities and can be used to power warning signals on a dark and rainy night to ensure the safety of people.

recently introduced self-powered anticorrosion system is the integration of triboelectric nanogenerator (TENG) and cathodic protection, which can realize energy harvesting and self-utilization. [9][10][11][12][13][14] Since it was first reported in 2012, [15] developments of TENG spurt. [16][17][18][19] Based on the coupling effects of triboelectrification and electrostatic induction, TENG has the excellent ability to collect various types of energy and convert it to electric energy, including bioenergy, wave energy, raindrop energy, wind energy, and mechanical energy. Besides, TENG has the advantages of high voltage, low cost, and especially high reliability, robustness, and adaptability. [20,21] TENG has already been applied for small electronic equipment, clinical medicine, supercapacitors, sensors, etc. [22,23] Especially in the ocean, wave energy is huge, abundant, regardless of day and night. [24,25] Comparing with traditional wave energy harvesting technology-electromagnetic power generation, TENG possesses many advantages in converting wave energy into electrical energy, such as higher output power and energy conversion efficiency in low-frequency motion and fairly lower integration construction cost. [26,27] Constructing TENG device and applying it into cathodic protection is one important application of harvesting wave energy. [9] Cui and Wang designed contact-separation mode through modified materials and Zhao fabricated single-electrode mode TENG via polytetrafluoroethylene (PTFE) and electrodes array. [28] Many innovative materials are used to fabricate TENG and applied into cathodic protection, such as, PTFE/polyvinyl alcohol, [13] lead-free KNbO 3 /polyvinyl chloride, [29] hydrophobic A vertical contact-separation mode triboelectric nanogenerator (TENG) to collect mechanical energy and protect stainless steel from corrosion is constructed by spraying to combine MXene powder and polydimethylsiloxane (PDMS). The output of TENG increases significantly by spraying a very small amount (1.2 mg) of MXene, which has excellent conductivity and electronegativity. The MXene/PDMS TENG (MP/PP-TENG) shows the output performance with a short current circuit of 22 µA and output voltage of 900 V, and the output peak power increases by 2.6 times. Meanwhile, MP-TENG is a reliable alternative to power supply for cathodic protection. The electrochemical measurement results show that the open circuit potential drop of the stainless steel coupled with the MP-TENG is about 300 mV. Continuous motion of TENG can realize processive protection of metals, proving its potential practical application to all-weather marine corrosion protection.

As an energy-harvesting device, triboelectric nanogenerators (TENGs) have attracted much attention because they can harvest mechanical energy generated from multiple parts of the human body and easily supply energy to wearable devices. Here, we report a lightweight, portable, and wearable TENG device based on three-dimensional polypyrrole nanoarrays (3D PPy NAs), which can both collect mechanical energy and perform selfpowered sensing. 3D PPy NAs were fabricated by a facile electrochemical deposition method using carbon paper as the substrate, and different growth morphologies of PPy NAs were obtained by controlling the deposition time. Among them, the PPy NAs with a deposition time of 1000 s had the largest frictional effective area with the pores of poly(vinylidene fluoride) (PVDF), and the constructed PPy-PVDF TENG (2 cm × 2 cm) had the highest output performance, with an open-circuit voltage (V oc ) of 20.2 V and a short-circuit current (I sc ) of 1.3 μA, which are 2.35 and 2.17 times higher than those of the carbon paper TENG (Cp TENG), respectively. In addition, PPy-PVDF TENG can collect mechanical energy from different parts of the human body such as hands, feet, and armpits and realize human motion pattern monitoring and sensing. The device can light up 21 LEDs with the touch of a hand and successfully drive small electronic devices such as a wearable watch and a portable thermohygrometer by integrating the rectifier circuit with a capacitor. This lightweight and portable PPy-PVDF TENG device demonstrates great potential in the field of wearable devices and self-powered sensing.
