Abstract:
1. A method for increasing biosensor precision and/or accuracy, comprising: applying a pulsed input signal to a sample of a biological fluid, the pulses of the input signal separated by relaxations where the electrical signal is off; generating an output signal from a redox reaction of an analyte in the sample, where the output signal is responsive to the pulses of the input signal; measuring the output signal from the redox reaction of the analyte in the sample; normalizing the output signal from the redox reaction of the analyte in the sample, where the output signal is responsive to an analyte concentration in the sample; comparing the normalized output signal from at least two of the pulses separated by relaxations to at least one control limit, where the at least one control limit represents an acceptable variation of the normalized output signal; and generating an error signal when the normalized output signal is not within the at least one control limit.
