1. A thermal radiation modulation system, comprising:
a low emissivity layer comprising a plurality of distributed, strain-dependent cracks, the low emissivity layer comprising a polymer composite layer and a mirror-like metal layer with low emissivity covering a surface of the polymer composite layer;
an elastomer layer bonded to the low emissivity layer opposite to the mirror-like metal layer; and
optionally a stretchable heater, the stretchable heater is attached to the elastomer layer opposite to the low emissivity layer,
wherein a top surface of the low emissivity layer comprising the mirror-like metal layer has a lower emissivity relative to the elastomer layer.
