“…The output power density of the TENG component in the TEWEH was significantly higher than those reported in previous studies, which could be attributed to the advantages of the channel‐type ball structure. [ 51 ] This TEWEH achieved a breakthrough in the output power density of the EMG component compared with previous homogeneous harvesters. This is due to the reduced gap between the magnet and coil, allowing the coil to capture the magnetic field changes caused by any movement of the PM‐PTFE ball.…”

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.

The ocean, as one of the most important areas for human production and living, plays a vital role in transportation, food production, and energy supply. However, it is greatly desired to develop relevant advanced technologies to achieve efficient and safe ocean exploitation and utilization. The advanced triboelectric nanogenerator (TENG), which can transform mechanical motion into electric energy to achieve the harvesting of related mechanical energy and obtain corresponding mechanical motion characteristics by the corresponding electronic signal, is a significant choice to develop the corresponding advanced technologies for marine exploitation. According to the application field, TENG based marine exploitation researches can be divided into three kinds of researching directions, which contain the in situ ocean energy harvesting, self‐powered ocean monitoring, and self‐powered marine electrochemical technologies. The latest representative research works, which are based on TENG technology for marine exploitation, are classified in detail and summarized comprehensively in this review. More importantly, the specific prospects of TENG in the marine exploitation are discussed in detail to promote future research.

Vortex-induced vibration (VIV) is a process that wind energy converts to the mechanical energy of the bluff body. Enhancing VIV to harvest wind energy is a promising method to power wireless sensor nodes in the Internet of Things. In this work, a VIV-driven square cylinder triboelectric nanogenerator (SC-TENG) is proposed to harvest broadband wind energy. The vibration characteristic and output performance are studied experimentally to investigate the effect of the natural frequency by using five different springs in a wide range of stiffnesses (27 N/m < K < 90 N/m). The square cylinder is limited to transverse oscillation and experiments were conducted in the Reynolds regime (3.93 × 103 – 3.25 × 104). The results demonstrate the strong dependency of VIV on natural frequency and lock-in observed in a broad range of spring stiffness. Moreover, the amplitude ratio and range of lock-in region increase by decreasing spring stiffness. On the other hand, the SC-TENG with higher spring stiffness can result in higher output under high wind velocities. These observations suggest employing an adjustable natural frequency system to have optimum energy harvesting in VIV-based SC-TENG in an expanded range of operations.
