Study of thin film blue energy harvester based on triboelectric nanogenerator and seashore IoT applications

Water wave energy, also known as blue energy, is a promising clean and renewable energy to solve global energy crisis. Recently, triboelectric nanogenerator (TENG) is considered as one of the most efficient approaches for harvesting water wave energy. Here we introduced a thin film blue energy harvester based on liquid-solid contact triboelectric mechanism. With novel external U electrode including a bar electrode (B electrode) and a U-shape electrode (U electrode), the shielding effect from water is hugely minimized, and outputs are effectively improved. Moreover, a series of IoT applications aiming seashore area is studied and realized, such as functions of wave level warning, continuously powering and a wireless signals transmission.
