1. An analyte sensor configured for insertion into a host for measuring an analyte in the host, the sensor comprising:

  • a first working electrode disposed beneath an active enzymatic portion of a membrane;

    a second working electrode disposed beneath an inactive-enzymatic or non-enzymatic portion of a membrane; and

    a non-conductive material located between the first working electrode and the second working electrode, wherein each of the first working electrode, the second working electrode, and the non-conductive material are configured provide at least two functions selected from the group consisting of electrical conductance, insulative property, structural support, and diffusion barrier.
