This paper presents an ultrasonic piezoceramic sandwich transducer (UPST), utilised for ultrasonic field generation in water and cavitational effect achievement. This device will be used to produce enlargement of the bubbles, initiated by the incident shock wave on the calculus in the lithotripsy process. The piezoceramic sandwich transducer powered by a function/pulse generator type IWATSU SG-4511 converts the electrical signal in mechanical vibrations, which are propagated in water.
