1. An implantable electrochemical sensor for measuring an analyte concentration in a host, comprising:
a working electrode configured to measure a concentration of an analyte; and a silver/silver chloride reference electrode, wherein at least a portion of the silver/silver chloride reference electrode is covered with an enzyme layer, wherein the enzyme layer is configured, in vivo, to generate hydrogen peroxide upon exposure to a substrate, whereby the hydrogen peroxide regenerates silver chloride of the reference electrode such that a reference capacity of the reference electrode is increased. |
