Poled PVDF piezoelectric film with thickness of 28 um or 45 um or 110 um thick. Uniaxially oriented with high d31 of 29-31 pC/N. d33 is higher than 20 pC/N and modulus is > 2.0 GPa.
Metallized piezo sheet of PVDF film.
Roll-to-roll sputtered (70 nm or 200 nm)) copper +10nm nickel Cu/Ni electrode. Ni is used to prevent the oxidization of copper. The adhesion of the electrode to PVDF is very strong and it can easily pass tape peel test.
The ultrathin electrode provides additional reliability in long-term operation.
One sheet with size is 180 mm x 270 mm (for 28 um and 45 um) or 210 mm x 280 mm size (for 50um or 110 um thick). we also sell the film in short roll with width of 360 mm wide (or 420 mm wide for 110 um thick). We have capability to supply >100,000 m/year for film thickness of 28 um, 45 um, and 100-110 um thick.
also offer the 110 um or 50 um PVDF-CuNi film 1 m long (or any other longer length) at reduced price.
The CuNi electrode can be etched by 1% FeCl3/H2O solution for you to produce your own sensors/actuators.
Great for piezoelectric piezo eneregy harvesting, piezo sensors, microphones, flexible loudspeakers, actuators.
Also for electroactive polymer EAP actuator, soft actuator, robotics
Uniaxially oriented with high d31 (but almost no d32).
