Abstract: Fringe field-based capacitive proximity sensors are well-suited to detect the presence of both conducting and nonconducting objects. The configuration of electrodes within these sensors ...

Abstract: This article presents a highly sensitive proximity sensor with micrometer-scale resolution. The working principle is the change in the capacitance of a movable step-impedance resonator (SIR) ...
