1. A continuous glucose monitoring system comprising:

  • an orthogonally redundant glucose sensor, comprising;

    an optical glucose sensor including a lightguide on a first respective substrate and having a proximal portion that is disposed externally to a body of a user and a distal portion configured for internal placement in the user'"'"'s body, wherein the optical glucose sensor includes an assay having a glucose receptor, a glucose analog, and a first fluorophore; and

    a non-optical glucose sensor including at least one electrode on a second respective substrate and having a proximal portion that is disposed externally to the user'"'"'s body and a distal portion configured for internal placement in the user'"'"'s body,wherein said first and second respective substrates are integrated into an integrated flex circuit, wherein said lightguide is disposed in an interior of said integrated flex circuit and said at least one electrode is disposed on an external surface of said integrated flex circuit;

    an insertion device including an insertion needle, wherein said integrated flex circuit is configured to be carried inside said needle for simultaneous insertion of said optical glucose sensor and said non-optical glucose sensor into the user'"'"'s body;

    a hand-held monitor having a display; and

    an external transmitter having a housing that houses the proximal portion of the optical glucose sensor and the proximal portion of the non-optical glucose sensor, wherein the transmitter includes instrumentation in said housing configured to receive an optical signal from the optical sensor and a non-optical signal from the non-optical sensor and configured to convert each of said optical and non-optical signals to respective glucose values, and wherein the transmitter is configured to wirelessly transmit said respective glucose values.
