Abstract

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.
