Latest Patents
One of Shiraishi's latest patents involves a limited current type oxygen sensor. This innovative sensor comprises a solid electrolyte element made from materials with high oxygen-ion conductivity, such as yttria-stabilized zirconia. The design includes electrodes on both the top and bottom surfaces of the element, formed by calcining a mixture of small ceramic particles and fine precious metal particles. A cover is provided over the second electrode, featuring at least one diffusion orifice that allows ambient gas to diffuse toward it. The sensor determines the dry-gas-based and humid-gas-based oxygen content by applying two different voltages to the electrodes, generating corresponding currents associated with the oxygen ions flowing through the electrolyte element. Additionally, a heater may be embedded in the electrolyte element to enhance the flow rate of oxygen ions between the electrodes.
