We demonstrated a new water motion active transducer (WMAT) without any external bias-voltage sources or additional processes, which critically limit the use of conventional passive capacitive transducers that convert mechanical into electric energy. From simple structure, we successfully turned on an LED using various kinds natural motion. The WMAT, has wide applicability, good potential to be candidate for generating sustainable
