Abstract
A capacitance pressure mapping system includes a plurality of sensor cells created by the intersection of electrode columns and rows, and a solid elastomer dielectric separating the electrode columns and rows. The elastomer is at least one planar sheet having a surface comprising a pattern of projections. There may be two sheets having opposing patterns of projections. The opposing patterns may be interlocking or corresponding.
