Abstract

The invention relates to damping of a sensor. A device comprises a substrate, a spring structure, and a first sensor. The first sensor is resiliently coupled with the substrate via the spring structure. The spring structure is configured to provide damping of the first sensor with respect to the substrate. The device also comprises a second sensor configured to sense a deflection of the spring structure.

Description

technical field [0001] Various examples relate to a device that includes a substrate, a spring structure, and a first sensor. The first sensor is resiliently coupled to the substrate via a spring structure. The spring structure is configured to provide damping of the first sensor with respect to the substrate. The device also includes a second sensor configured to sense a deflection of the spring structure. Background technique [0002] Microelectromechanical systems (MEMS) are desirable for sensing, for example, environmental pressure due to their compact integration capabilities and availability of flexible design options. The potential applications are enormous: navigation or positioning applications could benefit from correlating changes in environmental pressure with changes detected in the elevation of the corresponding device. [0003] However, it is known that changes in the sensor signal of MEMS pressure sensors may be caused by further external influences than c...
