Abstract: This paper provides an overview of the recent advancements in magnetic structured triboelectric nanogenerators (MSTNGs ) and their potential for energy harvesting and sensing in coastal bridge infrastructure. This paper begins with a brief discussion on the fundamental physics modes of triboelectric nanogenerators, triboelectric series, and factors affecting TENG power generation and transmission, providing a foundation for the subsequent sections. The review focuses on the different types of MSTNGs and their applications in coastal infrastructure. Specifically, it covers magnetic spherical triboelectric nanogenerator networks, magnet-assisted triboelectric nanogenerators, MSTNGs for bridges, and magnetic multilayer structures based on triboelectric nanogenerators. The advantages and limitations of each type of MSTNG are discussed in detail, highlighting their respective suitability for different coastal bridge infrastructure applications. In addition, the paper addresses the challenges and provides insights into the future of MSTNGs. These include the need for improved durability and sustainability of MSTNGs in harsh coastal environments, increasing their power-output levels to fulfill high energy needs, and the requirement for collaborative efforts between academia, industry, and government institutions to optimize MSTNG performance.
