Abstract:
A rotation rate sensor having a first structure movable with respect to the substrate, a second structure movable with respect to the substrate and with respect to the first structure, a first drive structure for deflecting the first structure with a motion component parallel to a first axis, and a second drive structure for deflecting the second structure with a motion component parallel to the first axis. The first and second structures are excitable to oscillate in counter-phase, with motion components parallel to the first axis, the first drive structure having a first spring mounted on the substrate to counteract a pivoting of the first structure around an axis parallel to a second axis extending perpendicularly to a principal extension plane, the second drive structure having a second spring mounted on the substrate to counteracts a pivoting of the second structure around a further axis parallel to the second axis.
