Claim 12:
13. A method of manufacturing a stretchable and transparent electronic structure comprising a plurality of laser patterned biphasic metallic grid lines having a thickness up to 600 nanometers and a width up to 6 micrometers, the structure comprising a stretchable elastomer layer, a metal alloying layer on top of the stretchable elastomer layer, and a liquid metal, wherein the structure is colorless and transparent when viewed under visible light, the method comprising laser patterning an electrically conductive material layer on the stretchable elastomer layer to form a plurality of void spaces therein, wherein the electrically conductive material layer comprises the liquid metal and at least one of the metal alloying layer and a metal adhesion layer, and wherein the electrically conductive material layer comprises the plurality of laser patterned biphasic metallic grid lines.
