  • Patent number: 8594760
    Abstract: The measuring system for in vivo monitoring of an analyte concentration with malfunction detection, comprises an electrode system, a potentiostat and an evaluation unit. The electrode system has a working electrode, a reference electrode, and a counter electrode. The potentiostat is for adjusting a difference of potential between the electric potential of the working electrode and the electric potential of the reference electrode to a specified value and for measuring an electric current flowing between the working electrode and the counter electrode. The potentiostat comprises a working electrode terminal for connection to the working electrode, a reference electrode terminal for connection to the reference electrode, and a counter electrode terminal for connection to the counter electrode. The evaluation unit monitors the electric potential of the counter electrode and generates a malfunction signal when said potential is outside a specified reference range. A method of operation is also disclosed.

  • Publication number: 20130277234
    Abstract: A method is disclosed for determining analyte concentration that includes applying a first electrical potential excitation pulse to a body fluid sample in an analyte sensor, and a first current response of the body fluid sample to the first pulse is measured. A second excitation pulse is applied to the body fluid sample in the analyte sensor, and a second current response of the body fluid sample to the second pulse is measured. An analyte level in the body fluid sample is determined by compensating for sources of error based on the first current response to the first pulse.
