Barycenter Self-Adapting Triboelectric Nanogenerator for Sea Water Wave High-Entropy Energy Harvesting and Self-Powered Forecasting in Marine Meteorology

As a high entropy energy (HEE), irregular seawater waves are a promising source of sustainable energy, and the development of matched harvesting technology is imperative to accommodate the new era. Here, a barycenter self-adapting triboelectric nanogenerator (BSA-TENG) that addresses these concerns and shows its applications as a distributed power source in isolated waters is reported. Benefitting from the physical gravity-guided structure design, random vibrational water wave HEE can be effectively converted into rotational mechanical energy and then converted into electric energy. In a nonlinear seawater wave pool, a unit delivers a peak power of 0.1 mW under a load resistance of 500 M omega when the working frequency is <1 Hz. On this basis, a self-powered temperature sensor system and wireless signal transmitter have been developed and driven entirely by the BSA-TENG. This work plays a key role in promoting ocean HEE harvesting and provides a workable way for a self-powered service system in seawater wave and marine meteorology monitoring and forecasting.
