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 200 nm thick sputtered 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
The electrode can be selectively removed by using a 9V battery or car battery and a needle. Will provide instructions.
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).
