Summary:PROBLEM TO BE SOLVED: To provide systems and methods for processing sensor data and self-calibration.SOLUTION: Systems and methods are provided which are capable of calibrating a continuous analyte sensor based on an initial sensitivity, and then continuously performing self-calibration without using, or with reduced use of, reference measurements. In certain embodiments, a sensitivity (110) of the analyte sensor is determined by applying an estimative algorithm (120) that is a function of certain parameters. The sensor property can be used to compensate sensor data for sensitivity drift, or determine another property associated with the sensor, such as temperature, sensor membrane damage, moisture ingress in sensor electronics, and scaling factors.SELECTED DRAWING: Figure 1A 【課題】センサデータ及び自己較正を処理するシステム及び方法を提供する。【解決手段】初期の感度に基づいて連続検体センサを較正すると共に、基準測定値を使用せずに或いは使用を減少させて自己較正を連続的に実行することができるシステム及び方法が提供される。特定の実施形態においては、あるパラメータの関数である評価アルゴリズム（１２０）を適用することによって検体センサの感度（１１０）が決定される。センサ属性は、感度ドリフトのためにセンサデータを補償するべく、或いは温度、センサ膜の損傷、センサエレクトロニクス内の湿気進入、及びスケーリングファクタといったセンサに関連付けられている他の属性を決定するべく、使用することができる。【選択図】図１Ａ
