Fuente: Wipo "Sensorization" An analyte monitoring system, comprising a sensor control device and an on-body electronics unit. The sensor control device has an in vivo analyte sensor adapted to sense a level of an analyte in vivo, wherein a first portion of the in vivo sensor is configured to be positioned beneath a skin surface of a user in a subcutaneous space and a second portion of the in vivo sensor is configured to remain outside the user. The on-body electronics unit is communicatively coupled with the in vivo analyte sensor and comprises a non-transitory memory, wherein individualized calibration information is stored in the memory, wherein the individualized calibration information is based on a representation of a measured manufacturing parameter of the in vivo analyte sensor, and wherein the individualized manufacturing parameter is an electrical characteristic and is specific to the in vivo analyte sensor.
