Abstract
An electro-conductive hydrogel composite material that may be suitable as an artificial skin satisfies all four requirements of artificial skin, namely, flexibility, electrical conductivity, healing property, and biocompatibility. The electro-conductive hydrogel composite material includes a hydrogel composition including water and a cross-linkable polymer which reversibly forms cross-linkage by hydrogen bonding; and an electro-conductive material dispersed in the hydrogen bond-based hydrogel.
