ABSTRACT:
Detector of the filament type for determining a static or dynamic charactstic of an ambient medium, constituted by a resistive component intended to be heated by the Joule effect in the medium, and an interface region suitable for reacting with the medium by a physico-chemical process 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.
