  • Electronic biosensor arrangement
    Patent number: 8043563
    Abstract: An electronic biosensor arrangement (1), comprising a receiving region (2) for biological material, a sensor-electrode arrangement (3) with sensor electrodes (3a, 3b) which intermesh in a comb-like manner being associated therewith, with which sensor electrodes (3a, 3b) a measuring circuit (5) is connectable for measuring an electrical measurement parameter on the sensor electrodes (3a, 3b) and influenced by biological material, wherein the sensor electrodes (3a, 3b) form a plurality of sensor capacitors (Csensor,1 to Csensor,N), with which electronic switching means (S2,1 to S2,N) driven by a control logic (8) are associated for connecting to earth or to a voltage source carrying a measurement voltage (Vdrive), respectively, comprising a reference capacitor (Cref), to which a switching means (S1) driven by the control logic (8) and arranged for optionally connecting to earth or to the measurement voltage (Vdrive) is likewise assigned, wherein the capacitors (Cref, Csensor1?Csensor, N) are also combined to a
