1. A capacitive image sensor, comprising:

  • a plurality of sensor electrodes that are disposed within a sensing region, wherein the sensing region includes a plurality of unit cells of a sensing pattern, and wherein a subset of the plurality of sensor electrodes comprises;

    a first sensor electrode disposed on a first surface of a substrate, the first sensor electrode having a first dimension and a second dimension substantially perpendicular to the first dimension, the first dimension being greater than the second dimension; and

    two or more sensor electrodes of the subset of the plurality of sensor electrodes, the two or more sensor electrodes disposed adjacent to the first sensor electrode and on the first surface of the substrate, each of the two or more sensor electrodes being interdigitated with the first sensor electrode, wherein, within the sensing region, no jumper is coupled to any of the plurality of sensor electrodes.
