The principal motivation of this work is the development and realization of anemometers based butterfly structureelaborated by flash evaporation technique on polyimide substrate using Bi2Te3–Sb2Te3(P) and Bi2Te3– Bi2Se3(N) materials which best values of Seebeck coefficient (ô???(T)) at room temperature are found to be 240 ô??¤V/K and -220 ô??¤V/K, respectively. These anemometers are based on both Peltier and Joule effects. We elaborate a particular geometry in order to improve the sensitivity of butterfly structuresensors. Fabrication and evaluation of performance devices are reported 2.3°C of cooling of only one Peltier module device for an optimal current of Iopt = 18mA is obtained.
