  • Self-supporting thin-film filament detector, process for its manufacture and it applications to gas detection and gas chromatography
    Patent number: 5753128
    Abstract: Detector of the filament type for determining a static or dynamic characteristic of an ambient medium, constituted by a resistive component intended to be heated by the Joule effect in the medium, and an interface process region suitable for reacting with the medium by a physico-chemical with an effect, depending on the characteristic to be determined, on the electrical characteristic of the interface region, in which there is a supporting member through which there is at least one aperture and at least one filament including the resistive component, composed of one or more thin films and a central portion located in the aperture and end portions via which the central portion is connected to the supporting member.
    Type: Grant
