1. 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:
depositing a metal adhesion layer on the stretchable elastomer layer;
depositing the metal alloying layer on the metal adhesion layer; and
alloying the metal alloying layer and the liquid metal to form an electrically conductive material layer; and
laser patterning a pattern of the electrically conductive material layer to form the biphasic metallic grid lines.
