Moisture andd Temperature Regulation

Healing wymaga moist, warm (but not hot) environment. Chronic diabetic wounds often have dimished perfusion, leading to cooler skin temperatures and dry eschar. Smart bandages that monitor temperatur can alert caregivers if thee wound becomes too cold (indicating ischemia) or too hot (indicating infection). Moisture sensors provide feed for timely dressing changes, preventing both desiccation and maceration.
