Here, we report a new synthetic method for the realization of highly conductive and mechanically tough hydrogels with tissue-like modulus. We employed a template-directed assembly method, which enables the arrangement of a disorder-free, metallic nanofibrous conductive network inside a highly stretchable hydrogel network. The resultant hydrogel exhibits exceptionally high conductivity (247 S/cm), high stretchability (>600%), and tissue-like Young’s modulus (35 kPa). Furthermore, it can provide tough adhesion (800 J/m2) with diverse dynamic wet tissue after chemical activation. In addition, its biocompatibility in vivo was confirmed, which makes our hydrogel an ideal bio-interfacing electrode for bioelectronics.
