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.

“…In addition, in order to collect different forms of energy more effectively, hybridized nanogenerators are also developed [ 29 ]. Furthermore, because the output voltage and current signals can represent the various dynamic motions triggered by mechanism, the TENGs can also be employed as a variety of self-powered sensors, such as vibration [ 30 ], wind speed [ 31 ], flow rate [ 32 ], displacement [ 33 ], pressure [ 34 ], tilt [ 35 ], and wave [ 36 ] sensors.…”

With the development of intelligent ship, types of advanced sensors are in great demand for monitoring the work conditions of ship machinery. In the present work, a self-powered and highly accurate vibration sensor based on bouncing-ball triboelectric nanogenerator (BB-TENG) is proposed and investigated. The BB-TENG sensor consists of two copper electrode layers and one 3D-printed frame filled with polytetrafluoroethylene (PTFE) balls. When the sensor is installed on a vibration exciter, the PTFE balls will continuously bounce between the two electrodes, generating a periodically fluctuating electrical signals whose frequency can be easily measured through fast Fourier transform. Experiments have demonstrated that the BB-TENG sensor has a high signal-to-noise ratio of 34.5 dB with mean error less than 0.05% at the vibration frequency of 10 Hz to 50 Hz which covers the most vibration range of the machinery on ship. In addition, the BB-TENG can power 30 LEDs and a temperature sensor by converting vibration energy into electricity. Therefore, the BB-TENG sensor can be utilized as a self-powered and highly accurate vibration sensor for condition monitoring of intelligent ship machinery.
