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.
Triboelectric nanogenerators (TENGs) have attracted great attention in the distributed power sources field due to their ability to convert environment mechanical energy into electrical energy. However, the power density, durability, and humidity resistance of TENGs remain to be improved for large-scale application. Here, a noncontact constant-voltage triboelectric nanogenerator via charge excitation (ECV-TENG) is proposed to enhance the output performance, which first applies an adaptive-contact constant-voltage TENG as a charge pump and generates constant-voltage output via an elaborate noncontact phase-shift design. The ECV-TENG achieves an average power of 12.74 W m −3 Hz −2 and exhibits a long service life of over 2,000,000 cycles. Moreover, thanks to the humidity resistance of the constant-voltage pump and noncontact TENG, the ECV-TENG demonstrates a good humidity resistance at humidity up to 90%. This work not only promotes the potential applications of TENGs as a distributed energy supply but also provides new insights toward large-scale energy harvesting by TENGs.
