Abstract:
1. A biosensor system for determining an analyte concentration in a biological fluid, comprising: a measurement device having a processor connected to a pattern read device; a sensor strip including a counter electrode and a working electrode, the sensor strip further having an encoding pattern with at least two circuits, where each circuit forms a circuit pattern, and where each circuit pattern has a unique set of contact areas, each circuit pattern being separate from the counter electrode or the working electrode; where the measurement device and sensor strip implement an analyte analysis, where the analyte analysis has at least one correlation equation; where the pattern read device senses the at least two circuit patterns on the encoding pattern, the shape of the at least two circuit patterns corresponding to a mapping of a digital representation; where the processor determines calibration information responsive to the at least two circuit patterns; where the processor calibrates the at least one correlation equation responsive to the calibration information; and where the processor determines the analyte concentration responsive to at least one calibrated correlation equation.
