Abstract
A sensor electrode (SE) for a capacitive sensor device is designed such that the width of the sensor electrode decreases towards the center such that the capacity between the sensor electrode and an object (F) with constant distance between the sensor electrode and the object (F) substantially is equal in size for each position of the object (F) relative to the sensor electrode along a longitudinal axis of the sensor electrode. The sensor electrode may consist of a plurality of segments arranged in a strip with decreasing width towards the center of the electrode.
