Abstract
An R-foam having a surface with an electrically resistive ink layer that is continuous and an electrically conductive ink layer that is in a predetermined pattern. The resulting surface is thereby electrically modified to have a predetermined resistive taper across it according to a predetermined resistivity curve. The method of manufacturing the R-foam involves printing the ink layers to the surface in a predetermined pattern that results in the predetermined resistivity curve. The ink layers may be applied using silk screening, stamping, and ink jet printing techniques.
