Abstract 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 MΩ 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.
