Poled PVDF-TrFE Copolymer 80/20 piezoelectric film without electrode. Operation temperature up to 125 C.
d33 >25 pC/N (thicker film has higher apparent d33 of >30 pC/N), dielectric constant: ~8.0. Dielectric Loss: 2%
For Ultrasound Fingerprint Sensor in personal electronics or medical transducers
For applications where high temperature of 125 C is required during sensor fabrication or sensor operation.
Typical Resonance Frequency: 20 um thick ~54.8 MHz; 25 um thick ~44.8 MHz; 120 um thick ~9.54 MHz; 270 um thick ~ 4.25 MHz
For piezo sensors. ultrashound transducers, hydrophones
Size of the piezo film is 100 mm x 100 mm. Larger area of 210 mm x 250 mm can be produced at higher cost (about 4X cost of 100 mm x 100 mm size. for example $2,000 for 210mm x 250 mm x 20 um)
Gold electrode can be added to both surfaces with additional $150 charges
large size of 200 mm x 250 mm can be provided at higher cost
