“…High-frequency ultrasonic transducers are small in size and require high precision, which puts forward higher requirements for transducer design, materials, and technology. Figure 1 shows a schematic diagram of a typical structure of a common one-dimensional array ultrasonic transducer, its structure includes an array element, a matching layer, a backing layer, an acoustic lens, and an array element connection, and the array element prepared from piezoelectric materials is a transducer core components [9]. For the piezoelectric ceramic material ultrasonic transducer, the acoustic impedance of the piezoelectric array element (the product of the medium density and the speed of sound in the medium) is usually greater than the acoustic impedance of the matching layer and the backing layer, and at this time, the piezoelectric array element takes its fundamental resonance corresponding thickness.…”
