The study presents the development of the TLMG hydrogel, a biointerface platform that forms in situ and adheres robustly to irregular skin wounds, offering enhanced mechanical properties and real-time signal monitoring for advanced wound management. By integrating tea polyphenols/lignin microspheres, the hydrogel combines bioelectronic and bioactive interfaces, achieving strong adhesion (200 kPa), high ionic conductivity (0.27 mS cm–1), and mechanical stability. Tested in complex animal models and human trials, the TLMG platform demonstrated intelligent wound management, dynamic signal monitoring, and improved wound healing through immunomodulatory mechanisms, highlighting its potential for wearable healthcare systems.

The study presents a novel tannin-modified cellulose-polypyrrole nonwoven dressing (TA/Cell@PPy) designed to accelerate wound healing by combining antimicrobial protection with electrotherapy. The dressing utilizes tannic acid for antibacterial activity against S. aureus and E. coli, and conductive polypyrrole to enhance endogenous electric fields, promoting re-epithelialization. In vivo evaluations show that TA/Cell@PPy significantly speeds up wound closure through enhanced granulation tissue, optimized collagen matrix organization, and stimulated angiogenesis. Its biomimetic nanofibrous architecture ensures biocompatibility and prevents secondary trauma during dressing changes, offering a promising solution for complex wound management by addressing infection control and tissue regeneration simultaneously.
