  • Gas detection element
    Patent number: 11530992
    Abstract: A gas detection element for detection of a measurement target gas is provided. The gas detection element includes a gas detection layer including a chemochromic pigment; and a spacer. The spacer is permeable to the measurement target gas, is disposed on a first surface of the gas detection layer, and has an area smaller than an area of the gas detection layer.
    Type: Grant
    Filed: August 2, 2018
    Date of Patent: December 20, 2022
    Assignee: Nitto Denko Corporation
    Inventors: Namiko Suzuki, Hiroyuki Higuchi, Koichi Nakamura, Masaya Nishigawara, Nahid Mohajeri
  • Gas sensing element
    Patent number: 10996174
    Abstract: A gas sensing element includes a gas detection layer including a pigment, the gas detection layer including a first surface; and a backing material disposed on the first surface of the gas detection layer. When reducing gas causes the gas sensing element to change in color, a color change ?L* of the gas sensing element is greater than or equal to 5.

  • GAS DETECTION SYSTEM AND GAS DETECTION METHOD
    Publication number: 20200124579
    Abstract: A gas detection system includes (1) an output device configured to output data acquired by monitoring a gas sensing element including a gas detection layer including a pigment; and (2) an information processing apparatus configured to process the data output by the output device, wherein the information processing apparatus includes a determining unit configured to determine whether the gas sensing element has detected gas, based on the data, and a display control unit configured to display, on an indication element, information indicating a position of the gas sensing element that has detected the gas or information indicating a status of gas leakage determined based on the data, when the determining unit determines that the gas sensing element has detected the gas.
