    • A thermochromic mesh comprises a mesh where space units are formed; a black pigment layer which is placed on the external surface of the mesh; and a thermochromic liquid crystal layer which is placed on the black pigment layer. Multiple space units are formed to allow a fluid to flow in and out. The method for measuring the temperature of a flow field using a thermochromic mesh comprises as follows: a step S1 which places a thermochromic mesh inside a flow field; a step S2 which places a light source and a light exposure element in order to be separated from the thermochromic mesh placed in the step S1; and a step S3 which senses the color of the thermochromic mesh from the light exposure element placed in the step S2 and converts the color into temperature. The thermochromic mesh and a method for measuring the temperature of a flow field using the same can minimize a disturbance of flow regardless of flow field measurement position and flux change, and can measure the temperature distribution, by coating liquid thermochromic liquid crystals on a mesh in order to be installed on a flow cross section to be measured.
