In this paper, a multiwalled carbon nanotubes (MWCNT)-sheet-based infrared sensor is proposed along with an easy, simple, reliable, and low-cost fabrication process that does not require manipulation of individual or bunches of MWCNTs or complex, expensive techniques such as photolithography. The output signal (resistance) is produced by a temperature change induced by infrared illumination. The authors found that the responsivity of the sensor could be improved by acid treatment. In addition, the density of the MWCNTs played a critical role in the performance of the sensor.
