英文摘要	While dynamic photonic materials have attracted much attention and there are well-known examples of color-changing species in nature, dynamic thermal control via modulation of optical properties has made relatively little progress. By replicating unique properties of desert ants and chameleons, here we present a stretchable selective emitter based on corrugated nickel that can modulate the emissivity to provide dynamic thermal control on human bodies. By evaporating nickel on a pre-strained polymer, we create 700-nm periodic corrugations that increase the nickel absorptivity from 0.3 to 0.7 in 0.2-2.5 mu m wavelengths due to multiple scattering, as supported by spectroscopy and computations. The optical change is reversible and accompanies ambient surface temperature variations in 305-315K. We demonstrate a wearable system, and the corrugated nickel on a human body at 309K allows a heat flux of 62Wm(-2) out of the skin when stretched and 79Wm(-2) into the skin when released.
