Piezoelectric Film Sensors
Sensitivity (mV/ms
Supplied by Midas Components Ltd - 01493 602602 - www.midascomponents.co.uk
Pro-Wave now presents a series of mechnoelectrical sensors and detectors produced by
advanced piezoelectric polymer film
technology. The polymer film of
polyvinylidene fluoride (PVF2) exhibits a
conspicuous piezoelectric effect and also has
high compliance comparing with other
piezoelectric crystals or ceramic materials.
Because of its superior piezoelectric strain
constant (g value), 10-20 times larger than
piezoelectric ceramic, it is an ideal sensing
material for converting mechanical to electrical
energy.
