A pressure sensor is provided. The pressure sensor includes a magnetic sensor element configured to generate a signal based on a magnetic field sensed by the magnetic sensor element; a microelectromechanical system (MEMS) structure including a membrane configured to move, depending on a pressure applied thereto, relative to the magnetic sensor element; and a field influencing element configured to modify the magnetic field based on a movement of the membrane, wherein the field influencing element is arranged on the membrane.

Coupling a magnet with a MEMS device

Aspects of the embodiments are directed to coupling a permanent magnet (PM) with a microelectromechanical systems (MEMS) device. In embodiments, an adhesive, such as an epoxy or resin or other adhesive material, can be used to move the PM towards the MEMS device to magnetically couple the PM to the MEMS device. In embodiments, an adhesive that is configured to shrink up on curing can be applied (e.g., using a pick and place tool) to a location between the MEMS device and the PM. As a result of curing, the adhesive can pull the PM towards the MEMS device. In embodiments, an adhesive that is configured to expand as a result of curing can be applied to a location between the PM and a sidewall of the chassis. As a result of curing, the adhesive can push the PM towards the MEMS device. The adhesive can also secure the PM in place.
