Product Description
This is the PVDF piezo film used for PolyK Firefly. It is produced with high performance 110 um thick PVDF piezo film, capacitance about 1.8-1.9 nF. Total Size: 30 mm wide x 80 mm long.
This is a new design with larger active area, and with 100 mm long wires through more robust rivet connectors. circuits.
there is a 250 um thick PET backing layer.
Output is > 100 V from simple vibration.
It can also be used as a heavy duty vibration sensor.
Made with PolyK piezo PVDF film with high d31. The 110 um thick piezo film with silver electrode is a good material for energy harvesting due to its mechanical robustness and high output voltage: http://piezopvdf.com/pvdf-piezoelectric-film-120-um-thick-silver-ink/
Other sensor size can be produced upon request.
