Schematic illustration of the fabrication process for the embedded silver nanowire (AgNW) nanomesh transparent skin electrode. (a) The PMMA was first spin-coated on the SiO₂ substrate and baked on the hotplate. (b) A solution of AgNWs was spray-coated on the PMMA-coated substrate using spray equipment. (c,d) Mechanically pressurized to weld the AgNW junctions, then obtained the 2D Ag nanomesh. (e) Liquid PDMS was spin-coated on AgNWs/PMMA/SiO₂ substrate, and thermal curing. (f) Peel-off by itself from the SiO₂ substrate in hot DI water, followed by immersion of the AgNW-embedded PDMS/PMMA in acetone for remove the PMMA layer. (g,h) Subsequently rinsed with alcohol and DI water to form a free-standing AgNW-embedded PDMS film.
