Abstract
Systems and methods of use for continuous analyte measurement of a host's vascular system are provided. In some embodiments, a continuous glucose measurement system includes an electrochemical sensor incorporating a silver/silver chloride reference electrode, wherein a capacity of the reference electrode is controlled.
Claims11
An electrochemical sensor for measuring an analyte concentration in a host, comprising:
- a working electrode configured to measure a concentration of an analyte;
- and
- a reference electrode comprising a material that depletes during sensor use, wherein the material is configured to be regenerated during sensor use, and wherein a rate of material depletion during sensor use substantially correlates with a rate of material regeneration during sensor use over a time period.
