Poled PVDF piezoelectric film 28 um thick. Uniaxially oriented with high d31 of 29-31 pC/N. d33 is higher than 20 pC/N and modulus is around 2.7 GPa.
Metallized piezo sheet of PVDF film.
With ultra thick 500 nm thick sputtered copper +50nm Cr electrode on both surfaces.
The ultrathin electrode provides additional reliability in long-term operation.
One sheet with size is 100 mm x 100 mm
The electrode can be selectively removed by dilute FeCl3 to pattern your own sensors and 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).
