Smart Hydrogels in Wearable Electronics for Wound Treatments

Abstract The complexity of wound care is a significant clinical challenge today. To address this issue, researchers extensively study hydrogels as a next‐generation solution. Hydrogel is a moisture‐retaining and biocompatible material that promotes cell regeneration and accelerates wound healing. However, traditional hydrogel dressings focus on passive protection for wounds, lacking dynamic responsiveness, and controllable adjustment capability based on changes in wound condition. Smart hydrogels, especially when integrated with wearable electronics, have emerged as a revolutionary advancement in wound treatment. By incorporating sensing, responsive controlled release, and dynamic interactive design, smart hydrogels enable dynamic wound treatment, demonstrating notable advantages. The advancements of smart hydrogels within the field of wearable electronics are summarized, elucidating their innovative fabrication techniques, critical functional properties, and integration into intelligent wound care systems through wearable technologies. The recent progress of smart hydrogels for wound healing acceleration is emphasized, including the ability to dynamically adapt to the complex wound microenvironment and the role of real‐time monitoring of wound biomarkers.
