SnO2 Nanowire Based Aerosol Jet Printed Electronic Nose as Fire Detector [in press]

Abstract (englisch):
A smart fire detector preferably reacting before
smoke breaks out and providing information about the substance
going to start burning, is an unaccomplished hope for fire safety
authority since decades. Here, we present an easy to fabricate,
hence cheap, smell detecting electronic nose (e-Nose) which is
capable to operate as low cost smart detector for fire related
smells as an example application. Smell sensing in principle is
achieved by measuring the resistance pattern of 16 sub-sensor
elements combined on a single chip and a subsequent pattern
recognition technique using multivariate data analysis. The
sensing material of one single sub-sensor are SnO
2
nanowires,
fabricated in a high temperature condensation process and
dispersed on digital aerosol jet printed interdigitated Au
structure. Assisted by UV illumination, the basic chip
performance was characterized using laboratory gases, such as
synthetic air, Isopropanol, CO and Benzene and the detection ... mehr
