Poled PVDF-TrFE piezoelectric film without electrode. Thickness of ~1000 um, other thickness available upon request, high d33 >30 pC/N. d31 and d32 38 pC/N. High g33 voltage piezo coefficient (>450 V-m/N), good for hydrophone
high hydrodynamic piezoelectric response (underwater acoustic sensor receiver), significantly better performance than PVDF piezo sensors.
Dielectric Constant ~8.4, dielectric dissipation factor ~2% at 22 C and 1 kHz
Sell in 20 mm/20 mm sheet, with 250 um thick brass shim electrodes, with soldering tab
Ether electrode can be applied based on customer request. We can also machine it to different size and geometry, such as smaller pieces, ring structures, etc.
