Flexible Piezo Vibration Sensor (energy harvesting), PolyK PVDF
The PolyK piezo PVDF sensor can generate high voltage output under vibration or pressure or elongation. This is a 12 mm wide PVDF sensor with silver electrode, and simply laminated to a sprint steel sheet with 3M double sided tape. the vibration of one end generates oscillating high voltage output signal which decay following the decay of the vibration. The piezo PVDF is a great flexible vibration sensor (d31), even small vibration can generate strong voltage output (better than pure compression d33 mode). They can be produced in large area (.1000 m) with low cost www.piezopvdf.com
This is not only a vibration sensor, it can also convert the mechanical energy to electrical energy for energy harvesting.
If you have customized piezo PVDF or PVDF-TrFE sensors that were produced by Measurement Specialty (MEAS) or TE Connectivity or Piezotech-Arkema, and they stopped the customized sensor business, please contact us sales at piezopvdf.com. We produce the piezo film and we have in-house sensor fabrication machines in the USA.
