1. A system, comprising:
a substrate;
a carbon rich coating deposited onto a surface of the substrate, wherein the carbon rich coating comprises a non-conductive carbon region having a first carbon content characterized by its sp2 carbon and sp3 carbon; and
wherein the carbon rich coating comprises one or more laser treated carbon regions, wherein the one or more laser treated carbon regions comprise an electrically conductive induced pattern comprising at least one interconnect, wherein the electrically conductive induced pattern has a second carbon content characterized by its sp2 carbon and sp3 carbon, wherein the second carbon content comprises more sp2 carbon than the first carbon content, wherein a sheet electrical resistance of the one or more laser treated carbon regions is less than a sheet electrical resistance of the non-conductive carbon region.
