Abstract
A composite fabric having self-regulating Infrared emissivity includes meta fibers formed with optical nanostructures and an environment (temperature and/or moisture) responsive mechanism configured to adjust a relative disposition between the optical structures to control the electromagnetic coupling therebetween, thus regulating the infrared emissivity of the composite fabric to maintain a user of the fabric in a temperature/moisture comfort zone. The environment responsive mechanism may include a temperature responsive polymer layer on the fiber capable of expansion/shrinkage depending on the applied temperature, or a moisture responsive fiber changing its shape depending on the moisture level to affect spacing between the optical nanostructures.
