High Temperature Piezoelectric Materials

TRS high-temperature piezoelectrics are based on a unique formulation that exhibits both a high Curie Temperature and high piezoelectric properties. The material can be operated as a piezoelectric to about 400°C with properties similar to Type II and VI PZT. The material is ideally suited for severe environment applications in the aerospace, oil drilling and automotive industries.

Typical Commercial Uses

  • Acoustic transducers for oil well drilling tools
  • Accelerometers and gyroscopes for aerospace applications
  • Ultrasonic tools for severe environment space exploration
  • Vibration sensors, knock sensors, and actuators for automotive sensor/control systems

Performance Characteristics

  

TRS high temperature piezoelectric ceramics have high resistivity for good reliability to temperatures in excess of 400°C. Component sizes currently available are ~ 4 cm2 by 0.2 cm thick.

   

The material is a stable piezoelectric to about 400°C, 100°C higher than Type II PZT. Properties are stable with flat coupling response and gradually increasing piezoelectric coefficients and dielectric constant. Room temperature properties are equivalent to Type II PZT.
