Latest Patents

His latest patents include groundbreaking innovations in gas sensors and methods of manufacturing these devices. One notable patent details a gas sensor utilizing CuO as a p-type semiconductor. By incorporating sodium carbonate (Na₂CO₃) in excess of 1 wt % relative to CuO, the sensor's sensitivity to gases such as hydrogen (H₂), nitrogen oxide (NO), nitrogen dioxide (NO₂), and sulfur dioxide (SO₂) is effectively suppressed. This enhancement allows for increased selectivity for carbon monoxide (CO), along with providing sensitivity to carbon dioxide (CO₂). Furthermore, by adding sodium salts of tungstic acid or molybdic acid, sensitivity to CO₂ can be lowered in comparison to CO sensitivity, enabling the selective detection of CO in exhaust gases from gas-fired water heaters or combustion equipment. This innovation allows for the detection of incomplete combustion, showcasing Nagano's expertise in creating practical and efficient gas detection solutions.

Another patent focuses on the manufacturing methods of gas sensors. In this methodology, p-type and n-type semiconductors are strategically formed as thick films or spray-coated onto electrodes. These films are designed to be in mutual contact, allowing for accurate readings based on the concentration of flammable gas components in introduced gas. This invention demonstrates the versatility of using alternating current (AC) voltage for bias, providing further advancements in gas detection sensitivity and efficiency.
