Methacrylated Chitosan Methacrylated Poly(vinyl alcohol)-Based Hydrogel Patch for Long-Term Electrochemical Wound pH Sensing.

ABSTRACT: While every wound has the potential to become chronic, the risk is significantly higher in individuals with specific medical conditions. Given this inherent risk, continuous wound monitoring patches are beneficial for all wound types throughout the healing process, enabling the early detection and management of chronic wound development. In this work, we introduce an eco-friendly, hydrogel-integrated, capillary-driven wound patch designed for continuous pH monitoring. The hydrogel, synthesized from methacrylated chitosan and methacrylated poly(vinyl alcohol), provides antibacterial properties, tissue adhesion, and moisture retention, thereby supporting stable electrochemical pH detection. A paper-based, capillary-driven microfluidic layer facilitates fluid transport toward an evaporation p
