Progress in material science has allowed the control of different physical fields in a manner that would be unachievable with ordinary materials. The development of engineered materials (the so‐called metamaterials) to control the conductive heat flux has revolutionized the manner of manipulating thermal energy, and allowed the possibility of guiding the heat flux in ways difficult to accept for human intuition. In this context, the present communication is oriented to provide a brief review regarding the recent progress and developments in thermal metamaterials conceived to perform several conductive heat flux manipulation tasks. Deeply theoretical discussions concerning design methodologies are left a side, and we focus on the design and manufacturing feasibility of metamaterials for thermal cloaking and camouflage, heat flux concentration and inversion, among other applications that lead to the next generation of thermal devices.
