“…Therefore, the liquid-solid contact TENG demonstrated excellent performance and provided a novel approach to harvest different kinds of energy. [38][39][40][41][42][43] In this work, we rst presented a thermal-to-electric generator which combined a tube-based triboelectric nanogenerator and an oscillating heat pipe (TENG-OHP). In this new electric generator structure, the oscillating heat pipe harvested thermal energy and oscillating motion of the liquid plugs in the OHP was generated, resulting in the conversion of thermal energy into kinetic energy.…”

Ocean contain abundant clean energies including tidal and wave, but such energies are known for low frequency and large excitation amplitude, posing considerable challenges for high‐efficiency energy conversion. As an emerging technology, triboelectric nanogenerators (TENGs) have been widely used in energy harvesting and novel sensor design due to their high sensitivity and flexible structure. Meanwhile, they show great advantages in the low‐frequency environment (<5 Hz), and display great potential for deployment in remote ocean waters, and construction of large‐scale TENG networks. In this review, firstly, the working principle of TENGs and various configurations developed for the marine environment are introduced, which mainly include solid–solid and solid–liquid interfaces. Then, from the viewpoint of power improvement, authors are most concerned about the modification methods of materials such as surface modification, electron injection, and chemical doping. Meanwhile, improved technologies for energy harvesters in marine environment are discussed in detail, such as improving the hydrophobicity and degradation of materials, studying the self‐healing ability of materials, and designing power management circuits. Finally, the current challenges are summarized, and research trends are given from both short‐term and long‐term perspectives.

“…Ambient energy harvesting has emerged with great interest in applications for energy‐autonomous or battery‐powered systems with extended operating times. [ 1,2 ] Various ambient energy sources have been investigated, including mechanical vibration, [ 3,4 ] temperature gradient, [ 5 ] sunlight, [ 6 ] and chemical reactions. [ 7 ] Among these alternatives, mechanical energy is abundant in power, ubiquitously available from natural environments (wind and ocean waves), and compatible with human motion (walking and tapping).…”

Triboelectric nanogenerators (TENGs) have shown great potential as sustainable energy sources with the advantages of a lightweight, low cost, simple fabrication, and small size. Nevertheless, schemes for efficient power extraction from TENGs remains difficult, partly because of their short, high‐voltage (HV) pulse output. The available power from a single TENG is not usually enough for practical applications. An efficient power management system for TENGs using a dynamically reconfigured combining method and dual‐parameter maximum power point tracking (MPPT) is proposed. A series to parallel/parallel to series (SPPS) adaptive control method, which dynamically reconfigures the connection of multiple TENGs, efficiently combines the outputs. An MPPT method, which adjusts the dual parameters in a closed‐loop, provides a wide range for matching the high output impedance (≈MΩ) of TENGs. The proposed technique is implemented using a 416 nW energy harvester interface integrated circuit (EHI‐IC), realized using a 180 nm, 48 V Bipolar‐CMOS‐DMOS (BCD) process. Measured results show that the proposed approach achieves a 159‐fold improvement in power extraction compared to the results without EHI‐IC. Finally, a triboelectric energy harvesting ball (T‐EHB), which combines 12 TENG pairs for multi‐axis excitation, and several examples of device powering are presented using the T‐EHB.
