Piezotech® electroactive devices

Piezotech® produces electroactive polymer-based films, gauges, and patterned films that are individually and accurately poled using our unique poling process. Piezotech supplies high quality devices with reproducible and homogeneous polarization. Our process provides control of:

 

  • Electromechanical performance
  • Spontaneous polarization
  • Remnant polarization

PVDF gauges

Piezotech® provides PVDF gauges that are suitable for a wide range of sensing applications; e.g., detecting shock and/or pressure changes. Our unique process allows us to produce calibrated sensors with:

Piezotech piezoelectric gauge
  • High reproducibility
  • Rapid response (nanoseconds)
  • Large stress range (kPa to GPa)
  • Sensitivity (4µC/cm ² for 10GPa)
  • Flexibility at minimal thicknesses
