Özet

Polyvinylidene difluoride (PVDF) is a promising material for energy harvesting, sensors, and medicine applications due to its piezoelectric properties, flexibility, and biocompatibility. In this study, three methods for preparing thin PVDF films are explored: electrospinning, casting, and water-assisted fast curing. The films were incorporated into small, flexible sandwich-like structure generators, which can be used in energy harvesting systems or as sensors. These generators were tested for their electrical response to external mechanical deformation, allowing an investigation into the influence of production process parameters. The results showed that the strongest electrical response was observed in samples prepared by casting and electrospinning, while water-assisted fast curing was found to be less effective.
