Poled PVDF piezoelectric film without electrode. Thickness of ~3 um,
d33 >15 pC/N. d31 >25 pC/N as this film is uniaxially oriented. Size of 60 mm x 150 mm.
Note: it is difficult to use d33 meter to accurately measure thin polymer film. The measured value is usually lower than actual performance for thinner film. It is more appropriate to use d31 to characterize thin film <40 um.
Great for low-voltage piezo actuator and sensors.
For piezo sensors. loudspeakers.
