pvdf student pack


Research pack of PVdF contains:

  • 2 pieces of 40 micron PVdF poled, golded on both surfaces, size 5 cm x 5 cm
  • 2 pieces of 80 micron PVdF poled, golded on both surfaces, size 5 cm x 5 cm

Typical Uses

  • Pressure or impact sensors
  • Strain gauge
  • Simple microphones
  • Acoustic pickups


General properties relevant to all samples. Quarter and half wave thickness resonance frequencies for PVdF film can be deduced from the acoustic velocity and the thickness of the film.
