| Abstract: | A novel non-contact proximity sensor is proposed for detecting proximity of any kind of materials based on the displacement current effect.The sensor needs only single probe is simple and inexpensive,and is not influenced by static environment.It is sensitive in thickness and may detect objects'defects inside.The Area,shape of the sensor probe and the exploration distance can be designed arbitrarily by needs.The sensor may be applied in the micro-electromechanical system(MEMS),safe guard system,nondestructive exploration for material interior damage,etc. |
