  • Publication number: 20170343795
    Abstract: A micromechanical component includes an adjustable part, a mounting, at least one bending actuator, and a permanent magnet. The part is positioned on the mounting so as to be adjustable relative to the mounting about a first rotation axis and about a second rotation axis inclined relative to the first axis. The actuator includes at least one movable subregion. Movement of the subregion results in a restoring force that moves the part about the first axis. The part is connected indirectly to the magnet to be adjustable about the second axis of rotation via a magnetic field built up by the magnet together with a yoke device of the component or an external yoke. A micromirror device includes the micromechanical component. A method for adjusting the part includes adjusting the part simultaneously about the first and the second axes.
