Patent number: 11326969Abstract: A micromechanical sensor includes a substrate having a cavity; a flexible diaphragm spanning the cavity; and a lever element that spans the diaphragm and has a first and second end section on opposite sides of a center section. A first joint element is between the first end section and the substrate and a second joint element is between the center section and the diaphragm. The lever element can be pivoted due to a deflection of the diaphragm. Two capacitive sensors are provided, each having two electrodes, one electrode of each sensor being mounted at one of the end sections of the lever element, and the other being mounted on the substrate. The electrodes are disposed so that distances between the electrodes of different sensors are influenced oppositely when the lever element is pivoted. Also, an actuator is provided for applying an actuating force between the lever element and the substrate.Type: GrantFiled: December 8, 2017Date of Patent: May 10, 2022Assignee: Robert Bosch GmbHInventors: Stefan Zehringer, Andreas Duell, Arne Dannenberg, Helmut Grutzeck, Jochen Franz, Mike Schwarz, Soeren Zimmermann, Stephan Oppl

Publication number: 20200088598Abstract: A micromechanical sensor includes a substrate having a cavity; a flexible diaphragm that spans the cavity; and a lever element that spans the diaphragm and has a first and a second end section, the end sections lying on opposite sides of a center section. A first joint element is fitted between the first end section and the substrate and a second joint element is fitted between the center section and the diaphragm, so that the lever element is able to be pivoted due to a deflection of the diaphragm. In addition, two capacitive sensors are provided, each having two electrodes, one electrode of each sensor being mounted at one of the end sections of the lever element, and the other being mounted on the substrate. The electrodes of the sensors are disposed in such a way that distances between the electrodes of different sensors are influenced oppositely when the lever element is pivoted. Moreover, the sensor includes an actuator for applying an actuating force between the lever element and the substrate.Type: ApplicationFiled: December 8, 2017Publication date: March 19, 2020Inventors: Stefan Zehringer, Andreas Duell, Arne Dannenberg, Helmut Grutzeck, Jochen Franz, Mike Schwarz, Soeren Zimmermann, Stephan Oppl
