Haruki Matsuo is a prominent inventor based in Ageo, Japan. He has made significant contributions to the field of gas measurement technologies, holding a total of 2 patents. His work focuses on innovative devices that enhance the accuracy and efficiency of gas concentration measurements.

Latest Patents

Matsuo's latest patents include a gas concentration measuring device and a method for measuring the concentration of analyte gas in sample gas. The gas concentration measuring device features a heat generating resistor that produces heat when electricity is supplied, along with a stage that supports the resistor. The design ensures that the resistor and the stage overlap in plan view, with the stage having a plan view area of 3.6×10 μm or less. The ratio of the area to the total volume of the heat generating resistor and the stage, S/V, ranges from 0.0010 to 10 μm. This device is specifically configured to measure oxygen gas concentration in a sample gas based on the resistance of the heat generating resistor.

Another notable patent involves a solid electrolyte assembly that includes a substrate, a solid electrolyte, and both a first and a second electrode. The solid electrolyte exhibits oxide ion conductivity, while the first electrode, located beneath the solid electrolyte, contains a porous material. The design of the first electrode allows for a single oxygen diffusion path, which is formed by overlapping the substrate and the solid electrolyte. The relationship between the smallest cross-sectional area of the oxygen diffusion path and the area where the first and second electrodes overlap is defined by the ratio Sr/Sp, which ranges from 1×10 to 6.9×10.
