CONTINUOUS ANALYTE SENSOR WITH MAGNETIC ACTIVATION

An analyte measurement kit includes a sensor assembly having a transcutaneous sensor and a controller. The controller includes a battery that powers the sensor assembly and includes a magnetic sensor that generates an electrical activation signal in dependence of a magnetic field. The controller switches from a pre-operative state into an operative state upon generation of the activation signal. The sensor assembly releasably couples to an inserter. The inserter executes an insertion routine that advances the sensor assembly from a retracted position in which the transcutaneous sensor stands back behind a skin contact surface of the inserter into an advanced position in which the transcutaneous sensor projects beyond the skin contact surface, and subsequently decouples the inserter from the sensor assembly. The inserter includes an activation magnet. Executing the insertion routine changes the magnetic coupling between the activation magnet and the sensor assembly and thereby generates the activation signal.
