Abstract
In this paper we report on conductometric gas sensors based on suspended CuO nanowire arrays for CO detection in humid atmosphere. CuO nanowires with very small diameters (10nm - 30nm) are synthesized by a thermal oxidation process of Cu microstructures. Our approach allows efficient CuO nanowire integration using a CMOS backend compatible technology. We perform CO measurements in a concentration range between 25ppm and 150ppm and investigate humidity interference effects by comparing CO measurements in dry and humid atmosphere.
