Abstract
The two greatest difficulties humanity faces are environmental catastrophe and air degradation, and renewable energy from the ocean, solar, and wind offers a possible answer. This research describes a piezoelectric energy harvester (PENG) for harvesting low-frequency water wave energy. The poled PENG device based on a ferroelectric polymer polyvinylidene fluoride (PVDF) delivers a voltage of 32 V and a current of 130 nA. The PENG achieves a power of 1.38 µW at 500 MΩ. The low-frequency vibrations generated from the laboratory equipment were effectively converted into usable electrical energy. Furthermore, the output performance of four PVDF-based PENG units connected in parallel was placed inside a 3D printed housing after being exposed to water waves delivered a voltage of 1.1 V and current of 170 nA. This work presents an efficient approach for gathering low-frequency wave energy and realizing the blue-energy dream. This study offers a cost-effective approach for gathering low-frequency water wave energy and realizing the blue-energy vision.
