Abstract: A method for producing a heater with a co-sintered multilayer construction for a system for providing an inhalable aerosol, including providing at least one first substrate layer, arranging at least one first insulating layer at least in areas on the first substrate layer, arranging at least one heating element at least in areas on the first insulating layer, arranging at least one second substrate layer and at least one second insulating layer at least in areas on the heating element. The second insulating layer is arranged at least in areas on the second substrate layer, and the second insulating layer is in contact at least in areas with the heating element and/or with the first insulating layer. The method includes pressing the layers and the heating element, and firing the pressed layers in order to co-sinter the layers of the multilayer construction.

Abstract: A sensor unit for detecting a spatial temperature profile, having at least one substrate with a first surface and a second surface situated at least regionally opposite the first surface. The substrate is configured at least regionally to be flexible. At least one adhesion means is arranged at least regionally on the first surface and/or on the second surface for attaching the sensor unit to at least one measurement body. At least one sensor field is arranged on the second surface of the substrate. One aspect also relates to a method for producing a sensor unit.

Abstract: A sensor for the analysis of gases, with at least one housing having an internal space of the housing having a first opening and a second opening situated opposite it. At least one sensor element arranged in the internal space of the housing. At least one glass element and at least one encapsulating element arranged in the internal space of the housing in an intervening space between a housing wall in the internal space of the housing and the sensor element and fully surround at least regions of the sensor element. The glass element is at the first opening of the internal space of the housing and is adapted to hermetically seal the intervening space. The encapsulating element is arranged on the glass melting element in the direction of the second opening and is adapted to affix the sensor element in the internal space of the housing in a form-fitting manner.

Abstract: An Al2O3 carrier has a thin-film structure of platinum or a platinum alloy arranged thereon. The carrier and/or the thin-film structure are adapted to reduce mechanical stresses owing to different thermal expansion coefficients. The carrier and/or the thin-film structure include a surface of the carrier in the region of the thin-film structure is smoothed at least in sections to reduce the adhesion and/or a surface of the carrier has an intermediate layer on which the thin-film structure is arranged. The thermal expansion coefficient of the intermediate layer is from 8*10?6/K to 16*10?6/K, in particular from 8.5*10?6/K to 14*10?6/K, and/or the thin-film structure has at least one conductor path that is undular at least in sections, said conductor path extends laterally along the surface of the carrier.

Abstract: A method for producing a soot sensor is provided. The method includes steps of applying a contiguous metallic layer on an electrically insulating substrate and structuring the metal coating with a laser beam by vaporizing areas of the metallic layer. At least two interlaced contiguous electrically conductive structures are produced. The electrically conductive structures are spatially separated from one another with the laser beam and are electrically insulated from one another such that the conductive structures substantially extend next to one another and close to one another in an area relative to a total length thereof. A soot sensor produced using such a method is also provided. The soot sensor has an electrically insulating substrate and at least two contiguous electrically conductive structures which are spatially separated from one another and are interlaced as structured metallic layers. An intermediate space between the conductive structures is burned free with a laser.

Abstract: The present invention relates to soot sensors based on one-piece strip conductor structures, to methods for measuring soot, and to the use of heat conductor chips for soot measurement. For this purpose, the invention is based on the sensitivity of intensive variables, especially substance-specific variables. According to the invention, an electric soot sensor is provided, in which at least one chip is provided with at least one one-piece strip conductor having, in particular, two terminal panels, and the soot sensor has a soot determination facility that is adapted to determine an intensive or specific change of a surface. The inventive method is characterized by soot deposits causing a change of an intensive variable, especially of a thermospecific or electrical parameter of a chip, and by determination of said variable.
