We report on the fabrication of In2O3/multiwalled carbon nanotubes (CNTs) composite microstructures via inkjet printing. The active sensor materials were derived from an inkjet printed suspension of carbon nanotubes and molecular In2O3 metalorganic single source precursor onto Si, SiO2 or alumina substrates followed by thermal conversion and gas sensing measurements. We found a good correlation of printed microstructures (e.g. tracks 100-150 _m wide) with pre-defined programmed patterns and a homogeneous distribution of CNTs in the...
