Patent number: 11592413Abstract: A method for determining a nicotine content in a gas mixture. The method includes exposing a metal oxide-based sensor to the gas mixture, applying a temperature profile over time to the metal oxide so that the temperature of the metal oxide, proceeding from a predetermined first temperature level, is brought to a predetermined second temperature level under controlled first transition conditions, and the temperature is brought from the second temperature level to a third predetermined temperature level under controlled second transition conditions, ascertaining a transient specific electrical resistance of the metal oxide at at least one certain point in time during the application with the temperature profile, and determining the nicotine content based on the ascertained resistance.

Patent number: 9651512Abstract: A device, a method, and a use thereof for detecting a concentration of a gas or of a gas component. The device as a gas sensor includes at least one sensor element including a gas-sensitive layer and a heating element for heating the gas-sensitive layer. The heating element is able to heat the sensitive layer to a desired temperature prior to the detection and/or is able to maintain it at a desired temperature during the detection. The heating element allows the gas-sensitive layer to be outgassed if needed, so as to allow absorption again. To heat the heating element, there is a first contacting to which a first voltage may be applied. Moreover, subsequent to the heating step, a second voltage may be applied to the sensor element or to the gas-sensitive layer for measured value detection with the aid of a second contacting.Type: GrantFiled: June 25, 2014Date of Patent: May 16, 2017Assignee: ROBERT BOSCH GMBHInventors: Richard Fix, Denis Kunz, Philipp Nolte, Katrin Luckert
