Abstract

A new method of high-speed object detection using planar capacitive sensor was presented. The planar capacitive consists of two electrodes. A sine signal was applied on one electrode to form a quasi-electrostatic field and another electrode was use to detect the object signal. The voltage of the detecting electrode is changed when an object approached to the planar capacitive. The detection model of the planar capacitive sensor was established. The relationship between the rendezvous distance and the voltage variation was deduced. The increase of the electrode diameter and the decrease of the electrodes space contributed to the improvement of the capacitive sensor’s sensitivity. The experimental results showed that the planar capacitive sensor could achieve short range detection for high-speed object.
