Ultrasound Transducer Acoustic Stack:
Center Frequency: MHz
Sound Velocity in PZT: m/s
Dielectric Constant of PZT: ε
0
Area of the aperture: mm
2
Parameters: PZT thickness; |Z|; Stactic capacitance
Ultrasound transducer is a capacitor structure and static capacitance is determined by the area, dielectric constant, and thickness. The thickness is half wavelength at the design frequency. The transmit electrical impedance of the ultrasound transducer at the design frequency approximately equals to that of the static capacitor.
