Sound field distribution research of polymer materials ultrasonic probe chip polymer materials
Compared to the probe based on conventional piezoelectric ceramic,the high-performance ultrasonic probe made from polymer composite materials is much better,which has characteristics such as high sensitivity,wide bandwidth and good directional.And probes thickness electromeehanieal coupling coefficient KT value is up to 68%,which means it can reduce the crosstalk effectively to the phased array probe.In industrial,due to its high bandwidth,it has obvious advantages when used in coarse-grained materials testing and high-precision thickness measurement.In the medical field,ultrasound will reflex significantly at the impurities or the interfaces,and produce the Doppler effect in the flow of blood.Based on the sound field distribution comparative study of polymer materials ultrasonic probe chip,this paper proposed some polymer new applications in ultrasonic testing field.
