摘要
Biocompatible conductive hydrogels are progressively showing great significance in bioelectronics because of the porous structure, electronic transport capability, tunable mechanical properties and great biocompatibility, where materials with high conductivity, good mechanical properties, and easy processability are demanding. In this work, we develop hybrid conductive hydrogel consisting of γ-polyglutamic acid (PGA) and poly (3,4-ethylenedioxythiophene): poly (styrene sulfonate) (PEDOT:PSS), which shows good cytocompatibility, flexibility (~380 kPa stress, ~650% elongation) and conductivity (~12.5 S m−1). Especially, multiple hydrogen bonding interactions endows hydrates with adhesive performance, self-healing abilities and optimal injectable properties. In several proof-of-concept attempts, skin-like sensors fabricated by a facile molding-injecting method can successfully detect precise signals from human motions for healthcare monitoring and the understanding of the biological basis of a particular behavior.
