Abstract Diabetes significantly impairs the body's wound‐healing capabilities, leading to chronic, infection‐prone wounds. These wounds are characterized by hyperglycemia, inflammation, hypoxia, variable pH levels, increased matrix metalloproteinase activity, oxidative stress, and bacterial colonization. complex conditions complicate effective wound management, prompting development of advanced diabetic care strategies that exploit specific characteristics such as acidic pH, high glucose stress trigger controlled drug release, thereby enhancing therapeutic effects dressings. Among solutions, hydrogels emerge promising due their stimuli‐responsive nature, making them highly for managing these The latest advancements in mono/multi‐stimuli‐responsive smart showcase superiority potential healthcare materials, highlighted relevant case studies. However, traditional dressings fall short meeting nuanced needs wounds, adjustable adhesion, easy removal, real‐time status monitoring, dynamic release adjustment according wound's conditions. Responsive represent a significant leap forward proficient sensing responding environment, offering more targeted approach treatment. This review highlights recent dressing, delivery, emphasizing role improving healing. It addresses ongoing challenges future directions, aiming guide clinical adoption.
