Hydrogels are widely used in bioelectronics for the interfacing electrode between biology and electronics due to its excellent biocompatibility and tissue-like modulus. However, conventional hydrogels exhibit low conductivity and poor mechanical properties. In order to apply them for the interfacing electrode in bioelectronics, new materials strategy, which can simultaneously enable high electrical conductivity and mechanical toughness with tissue-like modulus, should be suggested. Here, I present a template-directed synthesis of conductive hydrogel that exhibits record-high conductivity (247 S/cm), highly stretchable (＞ 400%), tissue-like Young’s modulus (35~100 kPa) and high adhesiveness to tissue (~400 J/m2). We developed new synthetic route to build highly conductive and homogenous fiber network in the template polymer. Also, we successfully photo-patterned our conductive hydrogel and fabricated intrinsically stretchable electrode array.
