Abstract
The present invention relates to a measuring device and a method for contactless detection of an angle of rotation or a torsional rotation. The measuring device includes a first resonator () and a second resonator (). The two resonators () have an essentially circular circumference, on which at least one protrusion and/or one recess is disposed. The two resonators () are coplanar to one another and are also rotatable relative to one another. In addition, an exciter device () for exciting the resonators and a receiver device () for measuring a backscattered signal are present. Upon a relative rotation of the two resonators () to one another, the resonant frequency changes, which is used as a measure for ascertaining the angle of rotation.
