“…Ultrasonic transducers have been widely developed due to their versatile capabilities, high sensitivity, low impedance, and accurate investigative applications. As the core element of many exploratory systems, ultrasonic transducers have excellent properties in vast medical and engineering fields, including energy harvesting, nondestructive evaluation, underwater sonar, bone damage detection, physical acoustics, medical ultrasound technologies, son chemical and material characterization, aircraft [ 1 , 2 ], and many more. The development of the transducer is carried out by studying the main design parameters of the transducer, such as the matching layer material, piezoelectric stack, backing layer material, central frequency, transducer diameter, acoustic focal length, bondline thickness, bandwidth, and resolution.…”
