The schematic diagram of the EDGE process and multi-scale observation. (a) An oxygen plasma treatment to the PMMA substrate. (b) The electrospray deposition process of the AgNW solution with the patterned grounded electrolyte solution. (c) The patterned AgNW electrode by the EDGE process. (d) The comb-shaped AgNW electrode on a PMMA substrate by the EDGE process. (e) The enlarged image of the patterned AgNW electrode with a well-defined edge. (f) SEM image of the AgNW electrode. Scale bars are 500 µm (e) and 1 µm (f).
