1. A device comprising:

  • a first region extending along a first axis comprising a first bar shaped electrode extending along the first axis and within the first region, the first bar shaped electrode formed in a first layer of a capacitive sensor;

    a second region extending along the first axis comprising at least three bar shaped electrodes formed in the first layer of the capacitive sensor and formed within the second region, each of the at least three bar shaped electrodes extending along the first axis, each of the at least three bar shaped electrodes being distinct from one another such that no electrodes are present in the first layer between the first region and the second region, the second region parallel and adjacent to the first region, the second region distinct from the first region;

    a third region extending along the first axis comprising a second bar shaped electrode formed in the first layer of the capacitive sensor, the second bar shaped electrode extending along the first axis and arranged within the third region, the third region parallel and adjacent to the second region such that no electrodes are present in the first layer between the second region and the third region, the third region distinct from the first region and the second region; and

    a plurality of tracks configured to selectively couple electrodes within the second region and the third region.
