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 distal portion configured for internal placement in a body of user; and

    a non-optical glucose sensor including at least one electrode on a second respective substrate and having 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, and 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; and

    an external transmitter.
