Printable Conductive Hydrogels for Electrochemical Biosensing and Soft Bioelectronic Interfaces
Advanced Science, EarlyView.Flexible, conductive hydrogels that integrate printability, mechanical tunability, biocompatibility, and electronic performance remain challenging to achieve. Here, we develop 3D‐printable poly(ethylene glycol)–poly(pyrrole)‐ hydrogels with tissue‐like mechanics, high cytocompatibility, and robust electrochemical function.
