Poled PVDF piezoelectric film with different thickness: 8 um, 12 um, 16 um, 29 um, 28 um, 32 um, 45 um, 50 um, 100 um, 120 um, 200 um. Uniaxially oriented with high d31 of 29-31 pC/N. d33 is higher than 23 pC/N and modulus is >2.0 GPa.
With 100 nm thick sputtered aluminium electrode produced in roll-to-roll process. 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 210 mm x 270 mm
The aluminium can also be etched with dilute KOH water solution (or NaOH or HCl or vinegar) for producing sensors in university lab.
The 117 um thick piezo PVDF-Al has resonance frequency of 8.95 MHz (review test figure)
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).
