Ultrasonic transducer for use in e.g. medical catheter systems, comprises piezo-active transducer layer which is embodied as non-self-supporting layer

摘要

The transducer has a piezo-active transducer layer embodied as a non-self-supporting layer, contacting layers for electrically contacting the transducer layer, and a matching layer at the front for adjusting the acoustic impedance to a coupling medium. The matching layer of the ultrasonic transducer is configured as a supporting element for the transducer layer and the contacting layers making it possible to create a micro-system structure of the ultrasonic transducer which is provided with increased power output during transmission and added sensitivity during reception. An independent claim is also included for the ultrasonic transducer.
