Abstract

A long term analyte sensor for measuring at least one analyte in the body of a user and which includes a housing, a plurality of analyte contacting sensor elements and at least one structure for relaying information away from the sensor. This plurality of analyte contacting sensor elements are typically disposed in an array. The analyte sensor further includes at least one sensor protection membrane that is controllable in a manner such that sensor elements may be activated (e.g. exposed to the external environment) at different times so as to extend the useful life of the sensor. In illustrative analyte sensors, the analyte is glucose.
