Beschreibung
Zusammenfassung:	A MEMS device includes a layer stack having a plurality of MEMS layers arranged along a layer stack direction. The MEMS device includes a movable element formed in a first MEMS layer and arranged between a second MEMS layer and a third MEMS layer of the layer stack. A driving unit is further provided, comprising a first drive structure mechanically firmly connected to the movable element and a second drive structure mechanically firmly connected to the second MEMS layer. The driving unit is configured to generate on the movable member a drive force perpendicular to the layer stack direction, and the drive force is configured to deflect the movable member.
