Aiming to enhance the sensitivity of infrared image sensors, we evaluated the temperature coefficient of resistance (TCR) characteristics of single-walled carbon nanotubes (SWCNT) wrapped in polymers. SWCNTs with a diameter of 1.1 nm were wrapped with polyfluorene-bipyridine, and semiconductor-type SWCNTs were extracted. It was confirmed that thin-film transistors using a random network of these SWCNTs exhibited a large ON/OFF ratio (over 10^6) and a large TCR (approximately -10%/K).
