Polyvinylidene difluoride (PVDF) is a piezoelectric polymer with a low-cost, high flexibility and biocompatibility that is suitable for various energy conversion applications between the electrical and mechanical forms of energy. One of the novel techniques to create PVDF fibers is electro-spinning. In the present work, the above technique has been applied to develop electro-spun thin-film based on PVDF with the use of high electric field and a high-frequency mechanical vibratory motion as an electro-spinning setup. The high-frequency vibratory motion is used to create effective fluid viscous forces to achieve a localized fluid spreading and thinning behavior of extremely thin polymer fiber solution.
