Abstract :
In this work a fiber optic voltage transducer using oriented poly(vinylidene fluoride) (PVDF) films prepared by dip coating is presented. The device consists of an inner nanofilm of silver, an intermediate layer of PVdF and an external layer of Indium Tin Oxide (ITO). The metal layers were coated by sputtering, and they generate an electromagnetic resonance that produces an attenuation band, besides acting as electrodes. The fabricated transducer has demonstrated high sensitivity to the applied voltage showing wavelength displacements of up to 200 nm.
