elopment of Poly Vinylidene Fluoride (PVDF) sensors
for transducer applications
Long silver pattern Square silver pattern Grid pattern
Thick connector Comb like and spiral pattern
PVDF is a flexible, light weight, low (d33~ 14pC/N and g33
cost fluoropolymer, which works ~200mVm/N).
on the principal of piezoelectricity.
PVDF films are not available in It is useful for various applications
India. Indigenously developed such as pressure sensor, strain sensor,
films within the country is useful underwater sonar transducers,
for various engineering and bio- accelerometers, structural health
medical applications. monitoring, vibration sensors,
energy harvesting etc.
These films are prepared in micron
level thickness (30-60 micron) using Being flexible, it can be conformed
hot press, extrusion and solvent to any curved surface for sensing
cast methods with appropriate applications. It is stable towards
thermomechanical treatment to resisting moisture, most chemicals
obtain high piezoelectric coefficients oxidants and can be glued with
commercial adhesives.
