“…However, due to the electrostatic shielding, the overall electric output of the single-electrode TENG is only half of the dual-electrodes mode. However, the advantage of single-electrode TENG affords it a wide range of application prospects in movement monitoring and energy collection of water droplets, intelligent sensing, human-computer interaction and other fields [ 39 , 40 ].…”

Triboelectric nanogenerator (TENG), as a green energy harvesting technology, has aroused tremendous interest across many fields, such as wearable electronics, implanted electronic devices, and human-machine interfaces. Fabric and fiber-structured materials are excellent candidates for TENG materials due to their inherent flexibility, low cost, and high wearing comfort. Consequently, it is crucial to combine TENG with fabric/fiber materials to simultaneously leverage their mechanical energy harvesting and wearability advantages. In this review, the structure and fundamentals of TENG are briefly explained, followed by the introduction of three distinct methods for preparing fabric/fiber structures: spinning and weaving, wet spinning, and electrospinning. In the meantime, their applications have been discussed, focusing primarily on energy harvesting and wearable self-powered sensors. Finally, we discussed the future and challenges of fabric and fiber-based TENGs.

This paper proposes a highly integrated triboelectric‐electromagnetic wave energy harvester (TEWEH) that can efficiently collect wide‐frequency wave energy and realize a self‐powered marine buoy. The innovative design of a permanent magnet‐polytetrafluoroethylene (PM‐PTFE) ball ensures high integration between the magnetic material forming the electromagnetic generator (EMG) and the dielectric material forming the triboelectric nanogenerator (TENG). In the condition of swinging (1 Hz and ±30°), the output of the TENG component can reach 230.25 V, 1.34 µA, and the average output of the EMG is 2.30 V, 10.43 mA. Remarkably, even at an extremely low frequency (0.2 Hz), the TEWEH maintains exceptional output. The output power density of the TENG component and EMG component reach 13.77 W m−3 and 148.24 W m−3, respectively, which are much higher than in previous work. The TEWEH can quickly charge the 330 µF capacitor to a certain voltage, and then light up navigation mark lights and power thermometers. A sealed TEWEH with circuits works as a self‐powered marine buoy that can transmit actual marine ambient temperatures to land. In conclusion, the TEWEH has broad application prospects in the field of wave energy harvesting and the self‐powered marine Internet of Things.

“…Wang et al [ 38 ] reported a humidity-resistant, wind-direction-adapting flag-type TENG capable of collecting wind energy in the environment and serving as a self-powered wind-speed and wind-direction sensor. On the basis of the above, Zhao et al [ 39 ] modified the surface morphology of PTFE by sandpaper-grinding to improve the output performance, and systematically studied the effect of horizontal and vertical array arrangement on power output. However, the output performance of the single flag-type TENG needs to be improved.…”

Pervasive and continuous energy solutions are highly desired in the era of the Internet of Things for powering wide-range distributed devices/sensors. Wind energy has been widely regarded as an ideal energy source for distributed devices/sensors due to the advantages of being sustainable and renewable. Herein, we propose a high-performance flag-type triboelectric nanogenerator (HF-TENG) to efficiently harvest widely distributed and highly available wind energy. The HF-TENG is composed of one piece of polytetrafluoroethylene (PTFE) membrane and two carbon-coated polyethylene terephthalate (PET) membranes with their edges sealed up. Two ingenious internal-structure designs significantly improve the output performance. One is to place the supporting sponge strips between the PTFE and the carbon electrodes, and the other is to divide the PTFE into multiple pieces to obtain a multi-degree of freedom. Both methods can improve the degree of contact and separation between the two triboelectric materials while working. When the pair number of supporting sponge strips is two and the degree of freedom is five, the maximum voltage and current of HF-TENG can reach 78 V and 7.5 μA, respectively, which are both four times that of the untreated flag-type TENG. Additionally, the HF-TENG was demonstrated to power the LEDs, capacitors, and temperature sensors. The reported HF-TENG significantly promotes the utilization of the ambient wind energy and sheds some light on providing a pervasive and sustainable energy solution to the distributed devices/sensors in the era of the Internet of Things.
