Device and a method for detecting at least one analyte in a body fluid of a user

A medical device for detecting an analyte, comprising:

• a contact assembly, comprising:
• a first module having a plurality of first contact pads;
• a second module having a plurality of second contact pads, wherein
• the plurality of first contact pads and the plurality of second contact pads are each planar contact pads and the plurality of first contact pads are arranged at a perpendicular angle to the plurality of second contact pads;
• and
• a plurality of electrically conductive elastomer elements, wherein, for each electrically conductive elastomer element, one of the first and second contact pads exerts pressure to thereby deform the electrically conductive elastomer element, wherein deformation of the electrically conductive elastomer element results in the other one of the first and second contact pads being contacted by an exterior surface of the electrically conductive elastomer element whereby each of the electrically conductive elastomer elements electrically connects one of the plurality of first contact pads with one of the plurality of second contact pads;
• wherein the first module comprises a sensor for electrochemically detecting the analyte, the sensor having first and second opposing sides wherein at least one of the plurality of first contact pads is located on the first side of the sensor and at least another one of the plurality of first contact pads is located on the second side of the sensor such that at least one of the electrically conductive elastomer elements is positioned adjacent to and contacts the at least one first contact pad on the first side of the sensor and another one of the electrically conductive elastomer elements is positioned adjacent to and contacts the at least another one of the first contact pads on the second side of the sensor;
• and
• wherein the second module comprises an electronics assembly that has the plurality of second contact pads.

A method for electrically interconnecting two modules, the method comprising:

• providing a first module having a planar element with a first side and an opposite second side, the planar element having a plurality of first contact pads disposed thereon with at least one of the plurality of first contact pads being disposed on the first side and at least another one of the plurality of first contact pads being disposed on the second side;
• providing a second module having a plurality of second contact pads;
• providing a plurality of electrically conductive elastomer elements;
• arranging the plurality of first contact pads and the plurality of second contact pads nonparallel to one another;
• exerting pressure in a first direction onto the plurality of electrically conductive elastomer elements with the plurality of second contact pads to thereby deform the plurality of electrically conductive elastomer elements, wherein deformation of the plurality of electrically conductive elastomer elements results in an expansion of an exterior surface of each of the plurality of electrically conductive elastomer elements in a second direction transverse to the first direction such that the plurality of first contact pads are contacted by the exterior surfaces of the plurality of electrically conductive elastomer elements and each of the plurality of electrically conductive elastomer elements electrically connects one of the plurality of first contact pads with one of the plurality of second contact pads;
• and
• wherein each of the plurality of first contact pads and each of the plurality of second contact pads are planar contact pads which are contacted by the exterior surface of one of the plurality of electrically conductive elastomer elements and the plurality of first contact pads are arranged at a perpendicular angle to the plurality of second contact pads.
