Ultrasound Transducer Design

Smart Material offers engineering services for the modeling, development, production and testing of ultrasound transducers based on our various 1-3 piezo composite products.

We also offer various electronic amplifiers capable in driving different capacitive loads in various frequency ranges for Sonar, NDT and SHM applications.

Our area of expertise is the design and production of:

  • SONAR transducers and arrays, 100khz to 1MHz
  • Air Ultrasound Transducer, 40kHz to 200kHz
  • NDT Transducers matched to different load mediums, 500kHz to 10MHz
  • Flaw detectors / Thickness gauges (including delay line), 1MHz to 8MHz
  • Medical Single Element Transducers, > 2MHz

Our engineering services for designing complete Ultrasound Transducers include:

Transducer Modeling and Numerical Simulation

  • Calculation of the acoustical behavior of the 1-3 piezo composite transducer using analytical and numerical methods.
  • Design and calculation of matching and backing layers to improve bandwidth and acoustical coupling.
  • Optimization of fill factor and rod distribution of the 1-3 composite to improve overall acoustical performance
  • Electric impedance matching to improve energy transfer into the transducer and enhance bandwidth
