“…[154] Integrated into a thin flexible layer, high performance paired TENG was proposed by Deng et al for harvesting underwater current energy (Figure 12d). [155] To make the device can effectively operate even in deep water with the high pressure, gas packet exchange structure and rigid-flexible coupling deformation mechanism were used in the corresponding fabrication. The special array of TENG can make efficiently obtain energy from the water flow and the power density was improved by over 100 times for the current energy harvesting of TENG.…”

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.

“…The pendulum is oscillated by the ocean kinetic energy that causes oscillations in the rotor of the generator to produce a varying magnetic field that induces electrical energy in a coil 150 mW This approach enhances the power generation capability of the device at the optimum weight. The authors in [77] design a sophisticated paired TENGs system integrated with a thin layer having flexibility as a triboelectric surface and coupled through a rigid yet flexible mechanism. This ensures that it can withstand the high water pressure at a high depth.…”

In underwater acoustic wireless sensor networks (UAWSNs), energy harvesting either enhances the lifetime of a network by increasing the battery power of sensor nodes or ensures battery-less operation of nodes. This, in effect, results in sustainable and reliable operation of the network deployed for various underwater applications. This work provides a survey of the energy harvesting techniques for UAWSNs. Our work is unique than the existing work on underwater energy harvesting in that it includes state-of-the art techniques designed in the last decade. It analyzes every harvesting scheme in terms of its main idea, merits, demerits and the extent of the harvested power (energy). The description of the merits results in selection of the suitable scheme for the suitable underwater applications. The demerits of the addressed schemes provide an insight to their future enhancement and improvement. Moreover, the harvested techniques are classified into various categories depending upon the involved energy harvesting mechanism and compared based on the maximum and minimum amount of harvested power, which helps in selection of the suitable category keeping in view the power budget of an underwater network before deployment. The challenges in energy harvesting and in UAWSNs are described to provide an insight to them and to address them for further enhancement in the harvested extent. Finally, research directions are specified for future investigation.
