1. A process for making self-patterning substrates comprising:
providing electrically conductive traces on a substrate by: coating the substrate at least partially with at least a layer of complementary reactant electrically resistant reactant formulation exhibiting a higher electrical resistance with respect to final conductive traces generated for a given coating surface area and thickness; altering conductivity of the complementary reactant electrically resistant reactant formulation by applying energy from a source of energy to the layer to form the electrically conductive traces; and triggering a redox reaction leading to a formation of the electrically conductive traces, wherein the complementary reactant electrically resistant reactant formulation comprises at least one of precursors of metals, precursors of oxidizers oxidizing the complementary reactant electrically resistant reactant formulation, and precursors of reducers reducing the complementary reactant electrically resistant reactant formulation, and the precursors of oxidizers or the precursors of reducers are capable of not undergoing chemical reactions under a temperature in a range from 10 to 40° C.
