Design of the power amplifier for ultrasonic transducer excitation is presented. We assumed that the amplifier output impedance will be significantly lower than the transducer input impedance. Therefore we suggest to used the transformer as voltage step-up and impedance matching element. The transformer influence on the ultrasonic transducer bandwidth and the power transfer efficiency are analy...

A high-frequency ultrasonic transducer for copper or gold wire bonding has been designed, analyzed, prototyped and tested. Modeling techniques were used in the design phase and a practical design procedure was established and used. The transducer was decomposed into its elementary components. For each component, an initial design was obtained with simulations using a finite elements model (FEM)...

Created in 1917 to detect German U-boats, Paul Langevin’s piezoelectric quartz transducer remains the foundation of all modern ultrasonic techniques.

The ultrasonic transducers have numerous applications in industries, including medical probes for performing ultrasound scans. One of the significant drawbacks transducer is wastage a large portion energy, due to high acoustic impedance, while transmitting waves target object. present study aimed investigate material design piezo-composite and improve its performance. Different were simulated C...
