Abstract
A proximity sensor assembly includes a proximity sensor, an insulating layer, and at least one segmented electrode. The proximity sensor is configured to generate an electric field emanating from the proximity sensor assembly. The insulating layer is in overlapping contact with at least one surface of the proximity sensor. A segmented electrode having two or more segments is in overlapping contact with the insulating layer and overlapping the proximity sensor. At least a first segment of the segmented electrode is configured to direct the electric field emanating from the proximity sensor and at least a second segment of the segmented electrode is configured to direct the electric field emanating from the proximity sensor differently than the first segment.
