The cell can produce the temperatures between 0 and 100ºC that emit an infrared radiation in the LWIR (8-11 micrometers) region. The cellcomponents made of nanocomposite material and it is shown that the features of the cell %00-00 are higher than the commercial Bi1Te0 component. The technical aspect of the cell such as the emission wavelengths, rate of temperature changing, thermal contrast, ZT factor and so one discussed in thispaper and were determined by using the thermography, non-contact thermometry, radiometry, four probe ac method and temperature differentialواژگان کلیدیThermal, cell, infrared, nanocomposite, LWIR
