Abstract

The characterization of ceramics is essential for the optimization of ultrasonic transducers. To do this we must determine the functional properties of ceramics which are:

  • speed of vibration of longitudinal waves
  • kt = Coupling coefficient: indicates the ability of the ceramic to transform electrical energy into mechanical energy
  • the dielectric constant
  • electrical and mechanical losses
  • acoustic impedance

The electrical measurements allowed us to determine the functional properties of the ceramics available to us. We were able to refine the results thus obtained thanks to the digital simulator (KLM).
