Abstract
A bearing device for bearing a shaft having a bearing, a supporting structure for supporting the bearing and at least on piezoresistive sensor incorporated in the supporting structure in an integrated manner which is arranged in the flux region of the bearing apparatus is provided. The electrical resistance of the sensor is influenced by the vertical force of the bearing having effect on the sensor such that the vertical force of the bearing may be electrically tapped on the sensor. A corresponding method for determining the static and/or dynamic vertical bearing forces of the shaft bearing of a shaft and a rotor system for determining the vertical bearing force of a shaft bearing are provided.
