Abstract
A conductive hydrogel includes: a first monomer; a second monomer; a crosslinking agent; a photoinitiator; a wetting agent; an electrolyte; and deionized water, wherein the first monomer is a 3-sulfopropyl acrylate potassium salt, and the second monomer is acrylic acid. The conductive hydrogel has high adhesivity, conductivity and moisture-retaining capacity and low skin irritancy compared to conventional hydrogels because it has the optimum composition ratio.
