Abstract: The invention relates to temperature sensors, in particular high-temperature sensors, having an optionally coated substrate, at least one resistor structure, and at least two connection contacts. The connection contacts electrically contact the resistor structure, and the substrate is made of zirconium oxide or a zirconium oxide ceramic stabilized with oxides of a trivalent metal and a pentavalent metal. The substrate is coated with an insulation layer and the resistor structure and the free regions of the insulation layer, on which no resistor structure is disposed, are at least partially coated with a ceramic intermediate layer. A protective layer and/or a cover is disposed on the ceramic intermediate layer. At least one electrode may be disposed, at least at one connection contact, alongside the resistor structure on the substrate. The invention also relates an exhaust-gas system for controlling and/or regulating an engine, particularly a motor vehicle engine, containing these temperature sensors.

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: A sensor for detecting electrically conductive and/or polarizable particles, in particular for detecting soot particles, includes a substrate, a first electrode layer, and a second electrode layer, which is arranged between the substrate and the first electrode layer. An insulation layer is formed betweem the first electrode layer and the second electrode layer and at least one opening is formed in the first electrode layer and in the insulation layer, wherein the opening of the first electrode layer and the opening of the insulation layer are arranged one over the other at least in some segments in such a way that at least one passage to the second electrode layer is formed.

Abstract: A gas sensor for measuring the concentrations of gases includes a solid body electrolyte, at least three electrodes, and a closed chamber. The doped platinum includes at least 50% by weight platinum and the remainder includes at least one further element selected from the group of solid body electrolytes. In particular, the doped platinum includes between 0.5% by weight to 15% by weight ZrO2 and the remainder is platinum, or the pure platinum is 100% by weight platinum and the gold alloy comprises at least 50% by weight gold and maximally 50% by weight platinum. In particular, the gold alloy includes approximately 85% by weight gold and approximately 15% by weight platinum or the gold alloy comprises at least gold and platinum at a ratio of 85% gold to 15% platinum.
