Abstract

A rate-of-rotation sensor having a substrate and a first Coriolis element are provided, an excitation arrangement being provided for the excitation of vibrations of the first Coriolis element in a first direction, a first detection arrangement being provided for detecting a first deflection of the first Coriolis element in a third direction running generally perpendicular to the first direction; characterized by the first Coriolis element being developed as balancing rocker.
