Abstract
Chronic wounds present clinical challenges due to persistent inflammation, infection, and dysregulated tissue repair, often exacerbated by the passive nature of conventional wound dressings. Recent advancements in hydrogel-based wearable technologies have transformed these biomaterials into multifunctional platforms capable of integrating real-time monitoring and targeted therapy, ushering in a new era of intelligent wound care. In this review, we show innovative diagnostic and therapeutic strategies, including wound-monitoring devices and multifunctional healing-promoted platforms, highlighting integrated closed-loop systems that dynamically adapt treatments to wound microenvironments, thus merging diagnostics and therapeutics. Challenges in fabrication engineering and clinical application are discussed, alongside emerging trends like AI-driven analytics and 3D-bioprinted technology. By bridging fragmented research, this work underscores the potential of hydrogels to enable intelligent wound management.
