Product Description
Poled PVDF piezoelectric film with 11-12 um thickness. Uniaxially oriented with high d31 >25 pC/N. d33 is higher than 18 pC/N and modulus is >2.0 GPa.
With 30 nm thick 0.75 ohm/sq 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 100 mm x 100 mm or 200 mm x 280 mm size
The aluminium can also be etched with dilute KOH water solution (or NaOH or HCl or vinegar) for producing sensors in university lab.
You can easily cut the film with scissors or razor blade, though you may need to clean the cutting edges with NaOH/KOH/HCl to remove the aluminum along the edges to avoid short circuit. You can also use ultrafast UV laser to ablate the thin aluminum electrode without damaging the PVDF film.
Great for piezoelectric piezo microphones, flexible loudspeakers, actuators.
Also for electroactive polymer EAP actuator, soft actuator, robotics
Great for speakers

For other thickness, we have in-house sputtering machine and we can produce customized film thickness with aluminum, copper, siliver, or gold electrode.
There may be occasionally pinholes in the film which may form electrical short circuit. The pinhole will be marked before shipping and it does not affect making sensors and actuators with size of cm or inche.
Shipping is free for USA domestic customers. For international customers, we will charge $50 for UPS Air International shipping with tracking number [you may receive a second invoice for international shipping].
