A closed-loop theranostic patch designed for chronic wound care combines hydrogel dressing materials with flexible electronics to monitor wound status and dynamically adjust response. The approach targets a gap in standard care, where dressings often remain passive while wounds change in real time. The platform is framed as a step toward “active” wound management by connecting sensing and response in one wearable patch. If clinically validated, the device could improve time-to-detection for deterioration and reduce complications associated with chronic wounds. — Key takeaway: integrating monitoring and intervention into a single wound interface moves wearables closer to treatment-adaptive care rather than observation-only tools.
