Abstract
A hinge for a micromechanical and/or nanomechanical structure includes: a support, and a movable part in an out-of-plane direction. The hinge allows for the out-of-plane displacement of the movable part. The hinge further includes two torsion beams extending along the axis of rotation of the hinge, two bending elements mechanically connecting the movable part and the support and having at least one pair of a first and of a second beam parallel with each other and extending in a plane perpendicular to the axis of rotation, the first beam being connected to the support and the second beam being connected to the movable part, the first and second beams being connected to one another by a first connecting element at a longitudinal end, the two beams extending in the same direction from the first connecting element.
