Beschreibung
Zusammenfassung:	Ultrasonic piezoelectric transducer comprising a piezoelectric material having a profile whereby the transducer transmits and/or receives ultrasonic vibrations in a dilational (quasilongitudinal) mode. The profile is curved and includes a point of inflection. Possesses a vibrational peak in the frequency range 10 KHz-200 KHz. Construction is performed via profiling and tensioning the piezoelectric material.
