  • Patent number: 12163909
    Abstract: The present disclosure refers to a sensor assembly for an IVD analyzer, the sensor comprising two opposite substrates with at least one fluidic conduit for receiving a sample. The electrodes of different types of electrochemical sensors are arranged on the two opposite substrates facing the at least one fluidic conduit for coming in contact with the sample and determining sample parameters, wherein the counter electrodes and the reference electrodes are formed on one substrate and the working electrodes are formed on the opposite substrate. This achieves optimal sensor-working conditions in terms of a homogeneous and symmetrical electric field density and enables a sensor assembly with simpler geometry and smaller size.

  • Patent number: 9709520
    Abstract: The invention relates to a method for the electrochemical measurement of an analyte concentration in vivo, comprising a fuel cell with which the analyte to be measured is reacted catalytically with an enzyme contained in an enzyme layer and which supplies an electrical voltage, dependent on the analyte concentration to be measured, between an anode and a cathode, which voltage is measured. In the catalytic reaction of the analyte to be measured in the enzyme layer, a product is generated which, as fuel of the fuel cell, oxidizes on the anode and is reduced on the cathode. The invention further relates to a fuel cell for such a method.

  • Patent number: 7949477
    Abstract: The invention relates to a method for monitoring an arrangement for determining a concentration of an analyte in a body fluid. The determination of the concentration of the analyte by means of the arrangement involves a procedure in which the analyte from the body fluid passes through an interface and is transported in a stream of liquid into a flowmeter chamber, in which a measurement is carried out to determine the concentration of the analyte. The evaluation of the measurement takes place in a signal processor. The monitoring of the arrangement comprises the following steps: measurement of measured values of at least two correlated system parameters of the arrangement by means of a sensor system, and comparison of the measured values with limit values stored for each of the system parameters in a storage unit, to obtain a combination of at least two comparison results.

  • Publication number: 20110036153
    Abstract: The invention relates to a test element for the testing of a liquid sample. The test element includes a sample application area, a test field, a sample transport path extending between the sample application area and the test field and an actuator field including a electrically-conductive layer. The actuator field is switchable between a first state attracting the sample and a second state attracting the sample less by applying to the conductive layer an electric voltage that is different from an earth potential. The actuator field has a section that is arranged at about the same distance from the sample application area as the test field, measured along the sample transport path, such that a wetting of the test field by the sample can be controlled by applying a voltage to the actuator field.
