One aspect is a heating element for a system for providing an inhalable aerosol, including a base body with an electrically insulating material, a heating structure arranged on the base body, and a cover layer adapted to fix the heating structure on the base body. One aspect further relates to a method for producing a heating element for a system for providing an inhalable aerosol, to a system for providing an inhalable aerosol, and to a vaporizer unit for such a system.

Disclosed is a layered body comprising a polymer comprising repeating units having the general structure —CH—CHR—COOR— as defined herein, to a process for producing such a layered body, to a layered body produced by that process and to the use of a layered body for electrophysical measurements.

Self-adhesive electrode patch

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.

The present invention relates to a screen-printing paste composition for producing an electrical conductor arrangement, which screen-printing paste composition comprises particulate noble metal, comprising platinum and palladium, metal oxides, and organic binders and/or solvents, the proportion of the metal oxides in the screen-printing paste composition being 5 to 15 wt. %, based on the total amount of platinum and metal oxides. Suitable screen-printing paste compositions can be processed to form composite products by means of application to a substrate, subsequent drying and baking, which composite products can be used, for example, in particle sensors or heating devices. The particle sensors and heating devices thus produced are characterized by improved adhesion to the substrate at high temperatures and by conductivity, and demonstrated very good reproducibility of the electrical resistance in different production batches.

One aspect is a resistor component for surface mounting on a printed circuit board, including a ceramic substrate with a first side and an opposite second side. A sinterable metallization is at least in some regions arranged on the second side. A resistance element comprising a metal layer is arranged at least in some regions on the first side of the ceramic substrate with a first connection and a second connection. An insulation layer is arranged at least in some regions on the resistance element and the ceramic substrate. A first region on the first connection and a second region on the second connection remain uncovered by the insulation layer. A first contact pad electrically contacts the first connection via the first region, and a second contact pad electrically contacts the second connection via the second region. The first contact pad at least in some regions covers a first surface region of the insulation layer and the second contact pad at least in some regions covers a second surface region of the insulation layer, and the first and the second contact pads are arranged spatially separated from one another on the insulation layer.

At least a portion of the feedthrough is made of an insulator and at least one area forming an electrically conductive cermet pathway. The cermet pathway may include an electrically conductive metal. The wire may be at least partially connected to the cermet pathway so that the material of the wire forms a joint microstructure with the electrically conductive material in the cermet pathway.

A sensor, particularly an impedance sensor, for example a soot sensor, is provided which has two mutually electrically insulated electrodes, wherein at least one external electrode is formed from a composite of metal and inorganic oxide as a film pattern having a film thickness of 0.5 to 20 &#x3bc;m. The trace width of the film pattern and the spacing between the traces is 5 to 70 &#x3bc;m and the border region around the conductor trace edge varies less than 10 &#x3bc;m. Both electrodes can be arranged adjacent to each other as a film pattern in a plane. Preferably, the sensor has a heater. For mass production, electrodes are produced as a film pattern having a film thickness of 0.5 to 20 &#x3bc;m on electrically insulating oxide bases and, following full-surface imprinting of a metal powder and oxide-containing paste, the electrodes are structured particularly accurately as traces from the printed film. In particular, the film thickness of the printed film is reduced.
