A carbon nanotube phase-change nanocomposite with a hydrogel achieves giant temperature coefficients of resistance resulting from a phase-transition that directly changes the tunneling potential that electrons experience in moving between nearby nanotubes. The bolometric photoresponses of this material are studied and its giant responses to temperature and humidity give it great potential for sensor applications and uncooled infrared detection.
