Abstract
The invention relates to a measuring system for determining a force and/or a torque on a torque-transmitting shaft, wherein: the measuring system has at least three, in particular at least four, piezoelectric elements each having a preferred direction and each being arranged at different positions about a rotational axis of the shaft in a force flow transmitted via the shaft, said arrangement being such that a force of the force flow acts, in particular exclusively, on the piezoelectric elements; the preferred directions each lie parallel to or in a single plane which is intersected by the rotational axis; and the preferred directions of at least two, in particular at least three, of the piezoelectric elements are oriented neither parallel nor antiparallel to one other.
