US Patent 10908117 Low impedance sensor for low density materials

An electrochemical gas sensor device with small physical footprint is disclosed. The electrodes within the element are arranged about the electrolyte such that the electrical impedance of the sensor is minimized. This results in a fast stabilization after detecting gasses and enables rapid changes in bias voltage to target different gasses. Gasketing elements, or alternative designs, are included to eliminate the diffusion of gasses between the electrodes within the cell.
