Abstract

The system for measuring the concentration of a bioanalyte comprises a reagent and a processor communicatively coupled with an electrode and an induction device. An oxidation status of the electrode is modified by means of an oxidation-reduction reaction between the reagent and the bioanalyte, caused by an interaction between the induction device and the electrode. The processor is configured to: apply an electric current to an electrode path; determine a transmission time of the electric current applied to the electrode path; determine a lag between an expected transmission time and the determined transmission time for the applied electric current; determine the oxidation status of the electrode based on the determined lag; determine the concentration of the bioanalyte based on the determined oxidation status of the electrode.
