  • Patent number: 11782009
    Abstract: A method for determining a concentration of at least one analyte in bodily fluid, comprising: a signal generation step, wherein an excitation voltage signal is generated by a signal generator, wherein the excitation voltage signal comprises a poly frequent alternating current (AC) voltage and a direct current (DC) voltage profile, wherein the poly frequent AC voltage comprises at least two frequencies; a signal application step, wherein the excitation voltage signal is applied to at least two measurement electrodes; a measurement step, wherein a response is measured by using the measurement electrodes; an evaluation step, wherein an AC current response for each frequency and a DC current response are evaluated from the response; a determination step, wherein the concentration of the analyte is determined from the DC current response and from one or both of the phase and impedance information by using at least one predetermined relationship.
