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.

“…Previous studies on power management have been carried out using discrete components. [27][28][29][30][31][32][33][34][35][36][37] Considering the form factor for wearability, however, discrete realizations impose a significant limit on reducing the volume, size, and power. Consequently, the integrated circuit (IC) approach for TENG power management has attracted significant attention.…”

A self-powered system for the Internet of Things (IoT) is demonstrated for efficient energy harvesting of naturally available mechanical energy. In this system, new contact-separation mode triboelectric nanogenerators (TENGs), based on fluorinated ethylene propylene, are investigated using the segmented multi-TENG configuration to reduce the effect of parasitic capacitance. The TENG extraction is optimized using a unit step excitation involved with the Dawson function to achieve a high voltage (400 V) and a high current (26.6 µA). To fully extract the power of the TENGs, the power management integrated circuit (PMIC) specially designed for adaptively controlled, high-voltage (HV) maximum power point tracking (MPPT) is proposed. The PMIC implemented in a bipolar CMOS-DMOS 180 nm process can handle a wide input range (5-70 V) by consuming 420 nW. The MPPT control allows a wide range of impedance matching from 10 to 300 MΩ, achieving a tracking efficiency of up to 98.2%. The end-to-end efficiency of 88% demonstrates state-of-the-art performance. To supply a higher instantaneous power than that available from the TENGs, a duty-cycling technique is successfully demonstrated. The proposed energy harvesting system provides a promising approach to realizing sustainable and autonomous energy sources for various IoT applications.

“…[ 22 ] It requires a good design configuration of the floating harvesting/sensing device such that it can closely synchronize with the arbitrary nature of the water waves. Considering the arbitrary wave nature, various designs have been reported such as spherical‐shaped, [ 34 ] tubular‐shaped, [ 35 ] pendulum‐shaped, [ 36 ] ellipsoidal‐shaped (providing a path similar to the cycloid), [ 22,16 ] and many more. Although the spherical‐shaped devices can closely synchronize with the random water waves in 3D directions, the sharp curvature of the sphere restricts the movement of the inside ball magnet thus limiting the device's performance.…”

healthy swimming environment. Among the vital features of pool water, water pH, free Cl − contents, hardness, water conductivity, and water temperature are most critical for maintaining a healthy and safe swimming environment. [1] Free Cl − is used to attack invading contaminants in water. [2] However, insufficient content of free Cl − makes pool water susceptible to a variety of undesired effects from the born algae and becomes a harbor for water-borne diseases (such as diarrhea, E. coli, cryptosporidium, hepatitis, and skin infections) which may develop from the dispersed biological matters from animals such as body sweat, makeup, body oils, and urine (including pets). [3] Therefore, the pool needs enough free Cl − to kill unwanted pathogens and contaminants. But the
