The invention relates to a measuring system (1) for determining a force and/or a torque on a torque-transmitting shaft (3), wherein: the measuring system (1) has at least three, in particular at leastfour, piezoelectric elements (4a, 4b, 4c, 4d) each having a preferred direction (Va, Vb, Vc, Vd) and each being arranged at different positions about a rotational axis (D) of the shaft (3) in a forceflow transmitted via the shaft (3), said arrangement being such that a force of the force flow acts, in particular exclusively, on the piezoelectric elements (4a, 4b, 4c, 4d); the preferred directions each lie parallel to or in a single plane which is intersected by the rotational axis; and the preferred directions (Va; Vb; Vc; Vd) of at least two, in particular at least three, of the piezoelectric elements (4a, 4b, 4c, 4d) are oriented neither parallel nor antiparallel to one other. 本发明涉及用于确定传递扭矩的轴(3)上的力和/或扭矩的测量系统(1)，所述测量系统(1)具有至少三个、特别是至少四个压电元件(4a，4b、4c、4d)，这些压电元件分别具有优选方向(Va，Vb，Vc，Vd)，这些压电元件分别在围绕所述轴(3)的旋转轴线(D)的不同位置上以
