Parallel, separate, narrow tracks of nanoscaled cupric oxide, CuO, displaying a width of 100–150 μm were fabricated by inkjet printing using a molecular copper–keto‐acidoximato complex as the precursor for ink formulation. Printed patterns were obtained on various inorganic substrates, such as silicon, silicon dioxide, or alumina. Annealing temperatures of 180–200 °C were employed for the decomposition of the printed precursor into the pure nanoscaled CuO phase. The inkjet‐printed samples were cured at 450 °C to ensure their stability during gas‐sensor tests at elevated temperatures. The printed material showed considerable promise for miniaturized gas‐sensor cells and for the detection of low concentrations of carbon monoxide and hydrogen.
