Abstract: Abstract Piezoelectric transducers are used in the application of sending and receiving sound waves. The distance at which the sound waves can be transmitted is determined by the transducer frequency. Therefore, measuring the frequency becomes…

Abstract: In this article, a smart time-domain technique is presented for detecting flaws in concrete structures using embedded piezoelectric transducers. The method relies on the time-of-flight of ultrasound (US) waves generated and sensed by piezoelectric transducers…

Abstract: Multi-element piezoelectric transducers used in shock wave generators for disrupting kidney stones (lithotripsy) or ablating soft tissues (histotripsy) are emitting high amplitude burst waves of one to ten pulses. Thus, most of the signal is…
