PIEZOTECH is the sole source for PVDF Shock Gauges Sensors suitable for shock physics research.

PVDF sensor

Piezoelectric polyvinylidine fluoride sensors (PVDF) 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 RATIOPVDF shock gauge
• SENSITIVITY (4µC/cm ² for 10GPa)
• VERY THIN
• SIMPLE CIRCUITRY

PVDF Shock Gauges Sensors characteristics

PIEZOTECH is the sole source for PVDF sensors suitable for shock physics research. The important features available only with PIEZOTECH sensors include:

REPRODUCIBILITY

The sensors are all made from a high quality bi-axially stretched polymer material, poled by the patented Bauer process to provide a stable and consistent polarization. Sputtered gold over platinum electrodes permit precise active area measurement.

CALIBRATION

These are the only PVDF sensors that are supported by extensive shock calibration data. This data ranges from a few kPa to over 25 GPa, and have been verified by the repeated work of different experimenters.

USER SUPPORT

The PIEZOTECH staff has significant experience in all aspects of PVDF fabrication and use. We stand ready to support your experimental 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.
