Patent number: 10215726Abstract: A sensor element for detecting a level of a gas component in the measured gas or a temperature of the measured gas. The sensor element includes at least one solid electrolyte layer. The solid electrolyte layer has at least one plated-through hole. The sensor element further includes a conductive element, which produces an electrically conductive connection through the plated-through hole. In the plated-through hole, the solid electrolyte layer is electrically insulated from the conductive element by an insulating element. At least one opening region of the plated-through hole is stabilized against phase transition by a stabilizing element. The stabilizing element is made at least partially of a material, which includes a noble metal and an element selected from the group consisting of: V, Nb, Ta, Sb, Bi, Cr, Mo, W. A method for manufacturing the sensor element is also provided.Type: GrantFiled: February 20, 2015Date of Patent: February 26, 2019Assignee: ROBERT BOSCH GMBHInventors: Alexander Bischoff, Andreas Rottmann, Antje Taeuber, Frank Buse, Jens Schneider, Oliver Dotterweich, Peter Alt, Thomas Juestel

Patent number: 10132772Abstract: A sensor element, in particular for detection of a physical property of a gas, in particular for detection of the concentration of a gas component or of the temperature or of a solid constituent or of a liquid constituent of an exhaust gas of an internal combustion engine, the sensor element including, a solid electrolyte film and including, located oppositely from one another in its longitudinal direction, first and second end regions, the sensor element including outside the second end region, in particular in the first end region, a functional element electrically conductively connected to a contact surface disposed in the second end region on the outer surface of the sensor element, the contact surface having a rounding, which is a radius, on its side facing away from the first end region. The contact surfaces each include three sub-regions: head region, neck region, and body region.Type: GrantFiled: March 13, 2014Date of Patent: November 20, 2018Assignee: ROBERT BOSCH GMBHInventors: Marc Rosenland, Andreas Rottmann, Carsten Gallinger, Markus Lux, Frank Buse, Jens Schneider, Thomas Juestel

Patent number: 10036720Abstract: A sensor element for detecting a physical property of a gas includes: a first end region and a second end region opposing one another; a functional element in the first end region interior that is electroconductively connected to a contact area disposed in the second end region exterior; the electrically conductive connection between the functional element and the contact area having a conductor in the interior of the sensor element essentially extending in the longitudinal direction, and having a leadthrough that essentially extends orthogonally to the longitudinal direction of the sensor element. The ratio between an electrical resistance of the conductor and an electrical resistance of the leadthrough is between 3 and 1/3.Type: GrantFiled: March 13, 2014Date of Patent: July 31, 2018Assignee: ROBERT BOSCH GMBHInventors: Andreas Rottmann, Frank Buse, Jens Schneider, Thomas Juestel
