Accelerate the shift to green energy with PVDF based piezoelectric nanogenerator

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.
