1. An analyte sensor system comprising:

  • a transcutaneous electrochemical analyte sensor comprising;

    a first portion configured to remain ex vivo during a sensor session; and

    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 an analyte concentration; and

    a membrane disposed over at least a portion of the electrode; and

    sensor electronics operably connectable to the transcutaneous electrochemical analyte 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 information based on a measurement of at least one sensor characteristic of the transcutaneous electrochemical analyte sensor during or after manufacturing of the transcutaneous electrochemical analyte sensor but prior to a sensor session;

    wherein the measured at least one sensor characteristic is associated with a thickness of the membrane.
