1. An implantable continuous glucose sensor comprising:

  • an elongated body configured to be transcutaneously implanted into a host, wherein the elongated body is bendable prior to sensor insertion into the host, the elongated body comprising;

    a substrate;

    a first sensor element covering at least a first portion of the substrate;

    a second sensor element covering at least a second portion of the substrate;

    a third sensor element covering a third portion of the substrate, wherein the first portion, the second portion, and the third portion are different; and

    a polymer membrane disposed over at least one of the first sensor element, the second sensor element, or the third sensor element, wherein the polymer membrane comprises an enzyme-containing domain;

    wherein the first sensor element, the second sensor element, and the third sensor element all share a same axis, wherein the same axis is the axis of sensor insertion; and

    wherein at least one of the first sensor element, the second sensor element, or the third sensor element is in contact with the polymer membrane.
