More detail

PVdF research kit contains:

  • 2 x 40 micron PVdF poled, golded on both surfaces, size 5 cm x 5 cm
  • 2 x 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.

Longitudinal acoustic velocity:2260 m/s
Melting temperature:175 ºC
Curie temperature: 205 ºC
Max operating temperature:70 ºC

40um and 80um PVdF

Metallisation: Approximately 250 nm Gold on top of 50 nm chrome
Film orientation: Uni-axially oriented film
Poling method: Poled as continuous roll via corona discharge
Poling uniformity: Some small-scale local variation
Approximate piezo coefficients: d31 = 27 pC/N, d32 = 5 pC/N, d33 =19.1 to 25.5 pC/N
Di-electric constant (relative permittivity): 4-12

We can also supply a small sample of 9 micron film at extra cost.
