  • Patent number: 11906456
    Abstract: According to one embodiment, a sensor element capable of detecting a target substance contained in an atmosphere is disclosed. The sensor includes a graphene, a drain electrode provided on the graphene, a source electrode adhered to the graphene, and a first substance provided on the graphene and having a charge condition. The charge condition is changed when irradiation of light and stopping of the irradiation of the light are performed. The target substance is detectable by measuring current that flows between the source electrode and the drain electrode. The measuring of the current is performed in a period during which the irradiation of the light and the stopping of the irradiation of the light are repeated above the sensor element.

  • Patent number: 11892386
    Abstract: An apparatus comprises a housing defining a chamber that has a liquid disposed therein, and a sensor submerged in the liquid. The sensor comprises a porous conductive film on a substrate, and the film comprises chemiresistive semiconducting metal oxide structures. The sensor also comprises an electrode pair operably connected to the porous conductive film for generating electric current in the film and for detecting a change in an electrical property of the film. The apparatus can be used to detect, identify, and quantify ions and molecules in a liquid sample. Molecules and ions, in a liquid sample, that interact with the porous conductive film can cause a change in an electrical property of the film. The change in electrical property of the film can be correlated with the presence and amount of the molecules or ions.

  • Patent number: 11867683
    Abstract: A method of analyzing dissolved gas in an oil-filled transformer includes determining a centroid of a polygon that represents a plurality of dissolved gas concentrations. A fault region in which the centroid of the polygon is located is determined, where the plurality of fault regions are defined in a composite fault region map that is a composite of a Duval Pentagons 1 and 2. The method classifies a fault experienced by the transformer based on the determined fault region within the composite fault region map. The classification is done by a machine learning classification technique. Further embodiments classify faults based on dissolved gas levels without determining a centroid of a polygon representing the dissolved gas levels. Related systems are also disclosed.
