Introduction：

Impedance analyzers are a class of instruments which measure complex electrical impedance as a function of frequency. This involves the phase sensitive measurement of current and voltage applied to a device under test while the measurement frequency is varied over the course of the measurement. Key specifications of an impedance analyzer are the frequency range, impedance range, absolute impedance accuracy and phase angle accuracy. Further specifications include the ability to apply voltage bias and current bias while measuring, and the measurement speed

An ultrasonic transducer/array is a crucial component of an ultrasonic scanner such as those widely used in clinical diagnosis . There has been a growing interest in transducers in the frequency range higher than 100 MHz for applications in single cell analysis, acoustic trapping, and studying mechanotransduction with improved lateral resolution . In these applications, a highly focused acoustic beam is required . When making highly focused ultrasonic transducers, those having a large aperture are much easier to press-focus. A transducer with a large aperture also generates a stronger pressure field under the same input parameters, such as voltage and pulse duration. Therefore, to generate the same acoustic pressure field, a transducer with a large aperture is safer and more effective than a transducer with a small aperture because lower input voltage and shorter pulse duration are needed.
