US Patent Issued on April 7 for "Method and apparatus for simultaneously measuring air contained hydrogen and water vapor concentrations via a single MEMS thermal conductivity sensor" (California Inventor)

ALEXANDRIA, Va., April 7 -- United States Patent no. 12,596,085, issued on April 7.

"Method and apparatus for simultaneously measuring air contained hydrogen and water vapor concentrations via a single MEMS thermal conductivity sensor" was invented by Peng Tu (Palo Alto, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A single MEMS thermal conductivity sensor based system capable of simultaneously measuring an air containing hydrogen and water vapor concentrations is described. The hydrogen and water vapor have different temperature coefficients of thermal conductivities and the sensor calculates their concentrations by their contributions to the total thermal conductivity of the air containing hydroge...
