Abstract:
1. A glucose sensor system comprising: an electrode configured to measure a concentration of glucose in a host, wherein the electrode comprises an exposed electroactive surface with an area of from about 0.000084 cm a membrane disposed over the electrode and configured to limit transport of glucose to the electrode; and sensor electronics operably connected to the electrode and configured to measure a current flow associated with the electrode, wherein the sensor electronics are configured to measure the current flow in at least a picoAmp range; wherein the system is configured to have a glucose sensitivity of from about 1 pA/mg/dL to about 25 pA/mg/dL, and wherein the system is configured to measure the current flow associated with the electrode with substantial linearity at glucose concentrations of up to about 400 mg/dL in a fluid with an oxygen concentration of less than about 0.6 mg/L.
