Sensor system for monitoring an analyte concentration in vivo and method for identifying a malfunction of such a sensor system |
摘要 |
<p>The system has a potentiostat (4) for adjusting difference of electric potential between a working electrode (1) and a reference electrode (2) to measure an electric current flowing between the working electrode and a counter electrode (3). The working electrode is connected to a working electrode terminal (15), and the reference electrode is connected to a reference electrode terminal (19). An evaluation unit (9) monitors the electric potential of the counter electrode, and generates a malfunction signal when the potential is outside a specified reference range. An independent claim is also included for a method for detecting malfunctions of a measuring system of an analyte concentration.</p> |
