1. A glucose sensor system comprising:
a transcutaneous electrochemical glucose sensor comprising:
a first portion configured to remain ex vivo during a sensor session;
a second portion configured to be disposed in vivo during the sensor session, wherein the second portion comprises an electrode configured to generate a signal associated with a glucose concentration; and
a membrane disposed over at least a portion of the electrode; and
sensor electronics operably connectable to the transcutaneous electrochemical glucose sensor, wherein the sensor electronics comprise a memory storing information associated with sensor sensitivity, wherein the information associated with sensor sensitivity is based at least in part on a membrane characteristic associated with the membrane measured prior to the sensor session;
wherein information associated with a shelf-life of the transcutaneous electrochemical glucose sensor after manufacturing the transcutaneous electrochemical glucose sensor and prior to the sensor session is monitored to ensure an accuracy of the sensor sensitivity is maintained over the shelf-life of the transcutaneous electrochemical glucose sensor, and wherein the transcutaneous electrochemical glucose sensor is exposed to an elevated temperature level relative to a predetermined temperature level when the information associated with the shelf-life of the transcutaneous electrochemical glucose sensor is monitored.
