DEVICE AND METHOD FOR TORQUE MEASUREMENT

The present disclosure describes a concept for torque measurement on a shaft. To that end, millimeter waves are transmitted in the direction of a first encoder structure, which is coupled to a first shaft section of the shaft for conjoint rotation and is arranged around the shaft, and in the direction of a second encoder structure, which is coupled to a second shaft section of the shaft for conjoint rotation and is arranged around the shaft. The first encoder structure and the second encoder structure are rotatable relative to one another in the case of a torque to be transmitted via the shaft. At least one reception signal is generated on the basis of millimeter waves reflected or transmitted by the first and second encoder structures. A torque transmitted using the shaft is determined on the basis of the at least one reception signal.
