Abstract: An assembly including a member made of a first material, which is axially driven into a circular aperture of a part made of a second material that is brittle, using an intermediate part made of a third material and mounted between the member and the part is disclosed. The intermediate part is a continuous cylinder including a hole for receiving the member so that the intermediate part absorbs radially and in a uniform manner, at least part of the axial driving force of the member. The part includes pierced holes forming elastic deformation units distributed around the circular aperture thereof for absorbing any of the radial force not absorbed by the intermediate part, so as to secure the assembly in a non-destructive manner for the part.

Abstract: The sensor system comprises an implantable sensor and a user device associated with it. A sensitive liquid is enclosed in the sensor, into which glucose can penetrate. The viscosity of the mixture of sensitive liquid and glucose is measured. The user device, which controls the measurement and its evaluation, is a portable device worn externally on the skin. The viscosity is measured based on the rotation of a measuring element driven by a driving magnet, both disposed in the sensor. The rotation of the measuring element is analyzed based on its decay behavior following switch-off of the driving magnet. In a second embodiment, the viscosity is measured based on the oscillatory behavior of an oscillating element excited to oscillate by a magnet, both disposed in the sensor. The oscillatory behavior is analyzed based on the decay behavior of the oscillating element following switch-off of the magnet.

Abstract: 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.
