PD ceramic offers competitive price for 80 Khz Ultrasonic Transducer(ultrasonic piezo sensor). Index Terms—capacitive diaphragm, micromachined, transducer, ultrasonic I. Figure 3 illustrates the piezoelectric effect. The principle is quite simple. the material induces voltage when the pressure or stress applied to it. Lead zirconate titanate (PZT) is the most commonly used piezoelectric material in ultrasound transducers. The presentation covers recent developments in invasive medical ultrasound transducers and transducer systems that employ the piezoelectric polymer technology for such applications as intraluminal imaging of the coronary arteries. The commands from the operator are translated into changing electric currents that are applied to the piezoelectric crystals in the transducer probe.
