摘要： The proposed sensor system comprises an implantable sensor (1′) and a user device associated with the latter. A sensitive liquid is enclosed in the sensor (1′), into which glucose can penetrate. The viscosity of the mixture consisting of the sensitive liquid and the glucose is measured. The user device, which controls the measurement and its evaluation, consists of a portable device worn externally on the skin. The viscosity is measured on the basis of the rotation of a measuring element (35) which is disposed in the sensor (1′) and which can be driven by a driving magnet (24) likewise disposed in the sensor (1′). The rotation of the measuring element (35) is analysed on the basis of its decay behaviour following switch-off of the driving magnet (24). In the case of a second exemplary embodiment, the viscosity is measured on the basis of the oscillatory behaviour of an oscillating element which is disposed in the sensor and which can be excited to oscillate by a magnet likewise disposed in the sensor. The oscillatory behaviour is analysed on the basis of the decay behaviour of the oscillating element following switch-off of the magnet.

摘要： A viscometer has a hollow cylinder mounted in a base frame and rotated about its longitudinal axis. A measuring part being flowed through by a fluid to be tested is rotatably supported in the hollow cylinder. An electromagnetic drive with a stator and a rotor for the hollow cylinder is provided, with which the hollow cylinder is rotatable. The stator is supported on the base frame and the rotor is supported on the hollow cylinder. An electromagnetic coupling of the stator with the rotor is provided by a ring rotor disposed between the stator and the rotor. The ring rotor is mounted about the longitudinal axis of the hollow cylinder so that the base frame and the hollow cylinder are decoupled with respect to the electromagnetic drive and a torque by the electromagnetic drive is applied to the hollow cylinder while the acting forces on the hollow cylinder are minimized.
