Abstract: Diabetic chronic wounds entail enormous psychological and economic burdens on diabetic patients. Traditional types of wound dressings lack diversity in their functions and do not have sufficient adaptability to the wound environment, which makes it difficult to meet the complicated needs arising during the healing process when they are used. Stimuli-responsive hydrogels respond specifically to the special environment of the wound area, for example, temperature, pH, glucose, etc., and achieve on-demand release by loading active substances, which effectively promotes diabetic wound healing. Herein, based on the research progress in stimulus-responsive wound dressings in recent years and the relevant work of our research team, we summarized and discussed hydrogel wound dressings responsive to temperature, pH, glucose, reactive oxygen species, enzymes, and multiple stimuli. Based on the special physiological environment of diabetic wounds, hydrogels with single or multiple stimuli-responsive properties can be designed so that they can release drugs on demand and improve the microenvironment of the wound, thus meeting the specific needs of different stages of wound healing. Although stimuli-responsive hydrogels currently show excellent therapeutic potential, there is still room for further development—cells or cytokines loaded in wound dressings usually act only at specific healing stages and the timing needs to be precisely controlled in order to avoid counterproductive effects on wound healing. In addition, the construction of sensor-therapeutic integrated devices for real-time monitoring of wound biochemical indicators so that drugs are release on demand and with precision to promote wound healing is also one of the topics that deserve more attention from researchers.
