Metamaterials or meta-structures are essentially a kind of artificially designed structures with certain specific physical properties or functions, which can often realize some special physical phenomena that natural materials do not possess. Thermal meta-structures can achieve some special thermal properties. Based on the transformation thermal theory and effective medium theory, this work realizes the thermal invisibility and heat flux manipulation through the integrated design of a double-layered thermal cloak meta-structure, with the flexible structural performance. The thermal simulation analysis of the thermal meta-structure was performed. The fabrication feasibility of the double-layered cloak meta-structure was studied by etching copper-clad film. Then, the thermal meta-structural properties were tested and analyzed using a self-built thermal test platform. The flexible thermal meta-structures have value in the field of human wearables and surface adaptation of geometrically complex objects.
