ABSTRACT:
An electrical system including a multi-layer conductive composition is disclosed. The multi-layer conductive composition includes at least a first composition, which may be a bottom composition layer, and a second composition, which may be a top composition layer, arranged on a substrate. The bottom composition layer has a greater level of conductivity than the top composition layer. In one preferred embodiment, the multi-layer conductive composition may be vertically conductive. In this preferred embodiment, the conductivity of the top composition layer may be selected so that electric current is permitted to flow along the z axis, but not along the x and y axes thereof. The electric current can flow along the x, y and z axes of the bottom composition layer. The top composition layer may mask the bottom composition layer. Further, the top composition may comprise a substantial amount of pigment so that multi-layer conductive composition has a desired color.
