Poled PVDF piezoelectric film 120 um or 45 um thick. Uniaxially oriented with high d31 of 29-31 pC/N. d33 is higher than 23 pC/N and modulus is around 2.7 GPa.
Metallized piezo sheet of PVDF film.
With 100 nm thick sputtered aluminium electrode. The adhesion of the electrode to PVDF is very strong.
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.
The aluminium can also be etched with dilute KOH water solution (or NaOH or HCl or vinegar) for producing sensors in university lab.
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).
