1. A biometric sensor, comprising:

  • a capacitive sensor array configured to image biometric data and formed on a first side of a substrate, the sensor array comprising;

    a first plurality of electrical traces defining a plurality of rows;

    a second plurality of electrical traces defining a plurality of columns, the plurality of columns intersecting the plurality of rows, thereby defining a plurality of intersections; and

    a capacitive sensing element formed at each of the plurality of intersections;

    at least one circuit formed on a second opposing side of the substrate and configured to communicate with the sensor array; and

    a plurality of vias extending through the substrate to electrically connect the sensor array to the at least one circuit;

    whereineach of the plurality of vias underlies an electrical trace chosen from the first or the second plurality of electrical traces.
