Solar‐Powered Radiation Cooling/Heating for Advanced Thermal Management of Wound

Active heating and cooling techniques are widely used in biological tissue regeneration. However, given the growing emphasis on environmental sustainability, heat exchange without additional energy input is receiving increasing attention. This Perspective examines the influence of temperature on wound healing and explores the potential of passive radiative cooling and passive radiative heating for thermal wound management. The advantages are highlighted, relevant application scenarios outlined, and current challenges identified, with the aim of proposing novel zero-energy wound treatment strategies for the biomedical field.
