Claim 21:
22. A method of making an electroactive circuit comprising:
a. forming on a substrate a pattern of solution-phase ink including electroactive material impregnated with solid-phase porogen particles, the formed pattern having a surface, and;
b. exposing at the surface of the formed pattern at least some of the solid-phase porogen particles without substantially changing the porogen arrangement in the pattern, wherein the exposing comprises controlling power, scan rate, and spot size of a laser relative to the pattern in a manner effective to both (i) etch the pattern along the surface of the formed pattern and (ii) anneal the pattern to additionally produce the engineered 3D porous electroactive architecture with additional pores, voids, and/or edge plane defects; and
c. removing at least portions of the at least some exposed solid-phase porogen particles to leave porogen pores to increase the ECSA of the formed pattern.
