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 thin sputtered copper/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.
One sheet with size is 180 mm x 260 mm
The electrode can be selectively removed by using a 9V battery or car battery and a needle. Will provide instructions.
Copper can also be removed with FeCl3 solution.
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).
