A Planar Capacitive Sensor Parameter Design for Security Detection

Abstract:

A planar capacitive sensor is designed for security detection. The different length of the sensor electrodes are design and the experiments are presented. For the relations between sensor structure parameters and the sensor potential distribution, detailed analyses are presented and the qualitative conclusions are discussed. The signal strength and measurement range of the sensor can be improved by enlarge the length of the sensor electrodes. The experimental results indicate that the sensor is more portable, easy to minimize, and applicable to the detection of a variety of sizes of containers. It is feasible to be applied to security detection.
