Abstract
Ultrasound transducers such as Capacitive Micromachined Ultrasonic Transducers (CMUT) have attracted attention recently because of their sensitivity, scalability, and compatibility with CMOS. They offer better bandwidth and sensitivity than piezoelectric transducers and have shown efficient transduction. The CMUT replaced piezoelectric transducer in some applications like imaging because of its lightness and miniaturization. In this work, the experiments were carried out to measure the length of the stainless-steel bar. Two methods were used to calculate the length of the stainless-steel bar using pulse-echo and transmission through (pitch-catch). The lengths were calculated with an error of 3.7% using the pulse-echo method and an error of 5.2% using the pitch-catch method. These experimental setups lay the foundation for ultrasonic nondestructive evaluation/testing using CMUTs. The results obtained using ultrasound signals were reliable for measuring the length and finding any defects in stainless steel.
