Piezoelectric polyvinilidene fluoride (PVDF) and polyvinilidene - co-trifluoroethylene P(VDF-TrFE) based sensors are the sensors of choice for a wide range of measurement applications because of their unique characteristics :

• RAPID RESPONSE (nanoseconds)
• LARGE STRESS RANGE (kPa to GPa)
• LARGE SIGNAL TO NOISE RATIO
• SENSITIVITY (4µC/cm ² for 10GPa)
• VERY THIN
• SIMPLE CIRCUITRY

The PIEZOTECH staff has significant experience in all aspects of PVDF and P(VDF-TrFE) fabrication and use. We stand ready to support your experimental and developement efforts.

We provide the guidance you need to apply the transducer to your experimentation or we can fabricate a complete transducer tailored to your needs.
