摘要: The invention relates to a rotational rate sensor comprising a substrate and a Coriolis element (2a, 2b), said Coriolis element (2a, 2b) being arranged over a surface of a substrate. According to the invention, stimulation means (12a, 13a, 12b, 13b) are provided for stimulating the Coriolis element (2a, 2b) in such a way that it oscillates parallel to a first axis (X); detection means (15a, 16a, 15b, 16b, 17) are provided for detecting a deviation of the Coriolis element (2a, 2b), caused by a Coriolis force in a second axis (Y) which is perpendicular to the first axis; the first and second axes (X, Y) are parallel to the surface of the substrate; sensor elements (1a, 1b, 2a, 2b, 3a, 3b) are provided which are at least partially mobile in relation to the substrate; and force-mediating means (19, 20) are provided for mediating a static force between the substrate and at least one of the sensor elements (1a, 1b, 2a, 2b, 3a, 3b).
