Summary: In this study, a flexible piezoelectric nanogenerator with tunable output power using a PVDF-CFO nanocomposite film was prepared. By incorporating ferromagnetic CFO nanoparticles into the PVDF matrix, the ferroelectric beta phase fraction of PVDF was enhanced, providing magnetic tunability to the PENG device. The output power of the PENG increased with the application of an external magnetic field, attributed to the decrease in resistance of the nanocomposite film.
