  • Patent number: 11287346
    Abstract: A pressure sensor system including at least one pressure sensor unit, the pressure sensor unit being configured with at least one sensor element which is situated in a cavity of a support structure, signal processing elements being integrated into support structure, the at least one sensor element being embeddable into the support structure to form the pressure sensor unit, and the support structure being formed by a land grid array/mold premold structure (LGA/MPM). The pressure sensor unit is introduced into a sensor housing to be provided with a diaphragm and is supported therein, a residual volume of the sensor housing, which is provided with at least one diaphragm and to the wiring of which the pressure sensor unit is electrically connected, being filled with an incompressible fluid. Also described is a method for manufacturing such a pressure sensor system and a measuring device.

  • Patent number: 10555090
    Abstract: A MEMS microphone system with encapsulated movable electrode is provided. The MEMS microphone system comprises a MEMS sensor having an access channel, a plug, and first and second members. The access channel configured to receive the plug is formed on at least one of the first and second member. A vacuum having a pressure different from a pressure outside the MEMS sensor is formed between the first and second members.
