摘　　要：综述压电材料传感器频率响应的主要影响因素和国内外对超高频传感器的研究发展状况,介绍工作尺寸等对传感器频率响应的影响规律。在此基础上,力求从规律中为得到一种1GHz以上的压电传感器指明方向,并结合无损检测技术应用到材料微结构、微缺陷的检测中,从而开辟压电传感器新的应用领域。The article summarizes influence factors of frequency response of piezoelectricity sensors and the research development of the ultrahigh frequency sensors in the world,the influence law of work size etc and frequency response of piezoelectricity sensors is introduced. Based on these factors,a kind of sensor whose frequency is more than 1GHz is intended to be designed. Combined with the technology of non-destructive testing,this sensor can be applied into material microstructure or microdefect testing and carves out a new appling field of piezoelectricity sensors.
