Progress in advanced electronics has initiated the investigation of new ways to develop and apply self‐powered smart devices. The concern for meteoric exhausting non‐renewable energy sources has spurred such endeavors. Even so, using external power sources like batteries is problematic due to limited capacity, maintenance inconvenience, replacement, and environmental hazards. Triboelectric nanogenerators (TENGs) capable of converting various forms of mechanical energies into electrical output are gaining popularity. The marine and coastal areas are abundant sources of salvable mechanical energy. TENGs can convert lower‐frequency, ununiform, multidirectional energies into usable electricity. This can solve the device‐powering problem and can generate diverse signals to act as monitoring or sensing platforms themselves. In this review, three main TENG‐based/TENG‐driven application themes are addressed, i.e., energy harvesting, marine environment monitoring, and self‐powered equipment for marine‐related activities. It attempts to emphasize that various design features of TENGs can influence output performance; TENGs can power devices and monitor ocean parameters; TENGs‐integrated modern IoT networking systems can transmit real‐time data. Overall, this review encompasses the fundamental working mechanisms, structure designs, and practical implementation scenarios of recently developed devices in diverse marine applications. Finally, the existing challenges and potential future directions for TENG‐based marine self‐powered electronic systems are discussed.

“…It can be observed that solid–solid CE, which has been studied the longest and has the best underlying theory, also has the most application scenarios. However, other states of matter have their own strengths, such as the unique application of solid–liquid CE in catalysis [ 140 ], and interfaces containing gases have a unique advantage in air purification [ 157 ].…”

The triboelectric nanogenerator (TENG) can effectively collect energy based on contact electrification (CE) at diverse interfaces, including solid–solid, liquid–solid, liquid–liquid, gas–solid, and gas–liquid. This enables energy harvesting from sources such as water, wind, and sound. In this review, we provide an overview of the coexistence of electron and ion transfer in the CE process. We elucidate the diverse dominant mechanisms observed at different interfaces and emphasize the interconnectedness and complementary nature of interface studies. The review also offers a comprehensive summary of the factors influencing charge transfer and the advancements in interfacial modification techniques. Additionally, we highlight the wide range of applications stemming from the distinctive characteristics of charge transfer at various interfaces. Finally, this review elucidates the future opportunities and challenges that interface CE may encounter. We anticipate that this review can offer valuable insights for future research on interface CE and facilitate the continued development and industrialization of TENG.

“…Volatile organic compounds (VOCs), which are primary constituents of atmospheric pollution, have the potential to interact with breathed air via processes such as evaporation or sublimation, hence posing risks to both the ecological environment and human health. , Hence, a significant area of focus in current research pertains to the development of effective detection methods and removal technologies for VOCs that pose environmental risks. These VOCs include xylene (C 8 H 10 ), acetone (CH 3 COCH 3 ), formic acid (HCOOH), acetic acid (CH 3 COOH), and formaldehyde (HCHO), as highlighted in previous studies. , Among these deleterious VOCs, formic acid is acknowledged as a significant VOC with detrimental effects. It possesses a diverse array of practical uses, such as serving as a preserving or antimicrobial agent.…”

Covalent organic frameworks (COFs) are a novel family of porous crystalline materials utilized in various advanced applications. However, applying COFs as a hazardous organic acid gas sensor is substantial but still challenging. Herein, a phenylenediamine-based covalent organic framework (TPDA-TPB COF) featuring excellent crystallinity, ultrastable thermal stability, and high surface area was successfully constructed. Then, the TPDA-TPB COF-modified quartz crystal microbalance (QCM) sensor is fabricated by immobilizing the TPDA-TPB COF thin film on the gold-QCM chip. The fabricated TPDA-TPB COF-modified QCM sensor demonstrates a rapid response, excellent reproducibility, high selectivity, and sensitivity to formic gas, arising from hydrogen-bonding interactions between formic acid and the outermost layer of the TPDA-TPB COF, as determined by extensive analysis and density functional theory calculations. The basic sites of the TPDA-TPB COF, which are numerous due to its high nitrogen content, and the carboxylic acid groups present in formic acid exhibit efficient interactions. The sensitivity of the TPDA-TPB COF-modified QCM sensor was found to be 7.75 Hz ppm −1 at standard room temperature and pressure conditions, with a limit of detection (LOD) of formic acid down to 1.18 ppm, which is significantly below the workplace olfactory threshold limit of 5.0 ppm established by the Occupational Safety and Health Administration. The TPDA-TPB COF-modified QCM sensor exhibits remarkable detecting capabilities, making it highly attractive for detecting organic acid vapors in diverse applications that require superior performance.
