Claim:
1. A force sensing assembly comprising: a generally planar first substrate having a conductor surface and an opposing touch surface; a plurality of parallel conductive traces on the conductive surface of the first substrate; an array of conductive patches oriented between adjacent parallel conductive traces and each patch is electrically connected to the conductive traces on the conductive surface of the first substrate; a generally planar second substrate having a conductor surface and an opposing touch surface; a plurality of parallel conductive traces on the conductive surface of the second substrate; an array of conductive patches oriented between adjacent parallel conductive traces and each patch is electrically connected to the conductive traces on the conductive surface of the second substrate; wherein the first substrate and the second substrate are oriented parallel to each other with the conductive surfaces of each substrate in apposition and the plurality of parallel conductive traces on the first substrate oriented perpendicular to the plurality of conductive traces on the second substrate; a plurality of insulating pads secured on the conductive traces on the first substrate where the perpendicular traces of the second substrate intersect the traces of the first substrate; and means for pre-loading the first and second substrate to create a pre-load force between the first and second substrate.
