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.

With recent advancements in technology, energy storage for gadgets and sensors has become a challenging task. Among several alternatives, the triboelectric nanogenerators (TENG) have been recognized as one of the most reliable methods to cure conventional battery innovation’s inadequacies. A TENG transfers mechanical energy from the surrounding environment into power. Natural energy resources can empower TENGs to create a clean and conveyed energy network, which can finally facilitate the development of different remote gadgets. In this review paper, TENGs targeting various environmental energy resources are systematically summarized. First, a brief introduction is given to the ocean waves’ principles, as well as the conventional energy harvesting devices. Next, different TENG systems are discussed in details. Furthermore, hybridization of TENGs with other energy innovations such as solar cells, electromagnetic generators, piezoelectric nanogenerators and magnetic intensity are investigated as an efficient technique to improve their performance. Advantages and disadvantages of different TENG structures are explored. A high level overview is provided on the connection of TENGs with structural health monitoring, artificial intelligence and the path forward.

“…Fourth, for maritime transportation [30][31][32][33] large ocean-going ships sailing on the sea inevitably shake due to the influence of wind, waves, ocean currents, and other environmental factors. Especially the heavy wind/waves and rough sea conditions [32][33][34][35] will pose a major safety hazard to maritime transportation. Therefore, it is necessary to monitor the conditions of ships on the sea in real time.…”

With the rapid development of transportation technology, people's lives are becoming more and more convenient, but the popularity of high speed transportation also increases the probability of emergencies. Therefore, it is necessary to conduct real‐time and accurate monitoring on transportation conditions to reduce the occurrence of emergencies. For possibly emergencies in other circumstances (e.g., meteorological disasters, geological disasters, and maritime disasters), emergency management is also critical to ensure the security of people and property. Prediction and early‐warning can help to detect abnormal situations and take measures, prior to potential risks. The basis of real‐time and effective transportation monitoring and emergency management requires a continuous and stable power supply for randomly distributed sensors and actuators. Triboelectric nanogenerators (TENGs) have been extensively investigated in different transportation circumstances to harvest the surrounding energy and drive distributed sensors for self‐powered wireless monitoring. This article surveys the research progress in TENGs in road transportation, bridge transportation, railway transportation, and maritime transportation, and related surrounding emergency management. Representative applications and the main achievements are summarized for these different application scenarios. A perspective on TENG research is given, and the remaining challenges facing TENGs in transportation and emergency management are discussed, along with potential solutions.
