Abstract: A micromechanical component. The micromechanical component includes: a mount; a displaceable part; and a first serpentine spring and a second serpentine spring which is embodied mirror-symmetrically with respect to the first serpentine spring in terms of a first plane of symmetry; a first actuator device and a second actuator device being embodied in such a way that by way of the first actuator device and the second actuator device, periodic deformations, mirror-symmetrical in terms of the first plane of symmetry, of the first serpentine spring and of the second serpentine spring are excitable; the micromechanical component also encompassing a first torsion spring and a second torsion spring that each extend along a rotation axis; and the displaceable part being displaceable, at least by way of the periodic and mirror-symmetrical deformations of the first serpentine spring and of the second serpentine spring, around the rotation axis with respect to the mount.

Abstract: An actuator device and a method for tilting an actuator device. The method includes the steps: conducting electrical current through an electrical conduction device, which is guided via a tilting device of the actuator device, within a first magnetic field that is generated by a permanent magnet device of the actuator device, so that an actuator element of the tilting device is tilted along a first tilting axis as the result of a Lorentz force; and generating a second magnetic field by an electromagnet device of the actuator device in the area of the permanent magnet device, so that the tilting device is tilted along a second tilting axis as the result of magnetic attraction and repulsion.

Abstract: A mechanical component has: a mounting; a movable part which, with the aid of at least one first spring and one second spring, is connected to the mounting in such a way that the movable part is movable about a rotational axis extending through a first anchoring area of the first spring on the mounting and a second anchoring area of the second spring on the mounting; a first sensor device with at least one first resistor which is situated on and/or in the first spring; and a second sensor device with at least one second resistor situated on and/or in the second spring. The first sensor device includes a first Wheatstone half bridge and the second sensor device includes a second Wheatstone half bridge. The first and second Wheatstone half bridges are connected to form a Wheatstone full bridge.

Abstract: A micromirror assembly is described as including a spring-mounted mirror and at least one stop unit, which is designed to restrict a movement of the mirror in the event of a movement of the mirror in a predefined direction out of its idle position. Furthermore, the invention relates to a projection device.
