ABSTRACT:
Because of their protracted inflammation, vulnerability to infection, and delayed healing, chronic wounds—such as diabetic foot ulcers, venous leg ulcers, and pressure ulcers—present a serious healthcare burden. Conventional wound care techniques frequently depend on subjective assessment and visual inspection, which may not yield timely and reliable information regarding the course of the wound. By combining wearable sensors, flexible electronics, and sophisticated medicine delivery systems into a single dressing, smart bandages have become a cutting-edge option. With the help of these devices, wound-related biomarkers like pH, temperature, oxygen levels, and moisture content may be monitored in real time, offering vital information on the condition of the wound and aiding in the early detection of infection or ischemia. Smart bandages provide an effective and individualized method of managing chronic wounds by facilitating remote monitoring and providing on-demand tailored therapy. The processes of wound healing, the drawbacks of traditional techniques, and the benefits of smart bandages in enhancing patient outcomes and maximizing therapeutic treatments are all highlighted in this paper.
