We study the optical properties of a polymer photonic membrane to keep the human body in thermal comfort. We show theoretically that the periodic structuration of the membrane with air holes modulates the optical response in the Mid-Infrared range. We found that the modulation of the optical spectrum allows to decrease the required ambient temperature by about 0.5 °C to maintain the normal skin temperature of 34 °C. The structured membrane is flexible and can easily be added to usual textiles.
