AN INVESTIGATION ON THE EFFECT OF BOTTOM LAYER MATERIAL ON THE VOLTAGE OUTPUT OF A PIEZOELECTRIC SMART WOVEN STRUCTURE

In this work, the voltage output of a 2-dimensional(2D) woven fabric produced by using polyvinylidene fluoride-based (PVDF) piezoelectric filaments into a plain woven fabric structure was studied. PiezoelectricPVDF filaments were produced via a method in which production and polarisation takes placesimultaneously. Produced filaments wereinvestigated under differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FTIR) to have an idea on the degree of crystallinity and β-phase content, respectively.A test sample was prepared by locating 2D piezoelectric woven structure between two pieces of indium tin oxide (ITO) coated polyethylene terephthalate (PET) film. The voltage output of the piezoelectric woven structure, which was placed on a steel or cork-like plate, was investigated by subjecting to a mechanical impact and the results were reported.
