Anemometer Based On Peltier Effect Deposed By Flash Evaporation

Abstract

ABSTRACT: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 ( (T)) at room temperature are found to be 240 V/K and -220 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 I opt = 18mA is obtained.

Thermoelectric behaviour of Bi-Te films on polymer substrates DC-sputtered at room-temperature in moving web deposition

“…Due to a poor mechanical flexibility of bulk inorganic materials, fabricating inorganic materials into thin-film form onto a flexible organic substrate is a promising option for flexible TEGs [15] . Various techniques have been reported in the literature for the fabrication of Bi2Te3 films, such as pulsed laser deposition [16,17], molecular beam epitaxy [18,19], metal organic chemical vapour deposition [20,21], electro-deposition [22], (co-)evaporation [23][24][25][26][27][28], and (co-)sputtering deposition [29][30][31][32]. The sputtering technique shows particular promise for scale-up manufacturing of TEGs: it is widely used in industrial manufacturing, being a continuous, stable and scalable process for making high quality films at moderate throughput speeds.…”
