This study presents the design and fabrication of carbon nanotubes (CNTs) film based temperature sensor. The sensor has been fabricated by the sequential deposition of thin layers of glue and CNT nanopowder on a paper substrate. The diameter of multiwalled nanotubes (MWNTs) varied between 10 and 30 nm. The ostensible thickness of the CNT films in the samples was similar to 30-40 mu m. The inter-electrodes distance (length) and width of the surface-type samples were 5 and 4 mm, respectively. The results revealed that the DC resistance of the sensors decreases in average by 10-20% as the temperature increases from 20 to 75 degrees C. The resistance-temperature relationship was simulated.
