Title
(EN) DUAL ELECTRODE SYSTEM FOR A CONTINUOUS ANALYTE SENSOR
(FR) SYSTÈME À DOUBLE ÉLECTRODE POUR UN CAPTEUR DE SUBSTANCE À ANALYSER EN CONTINU
Abstract
(EN)
Disclosed herein are systems and methods for a continuous analyte sensor, such as a continuous glucose sensor. One such system utilizes first and second working electrodes to measure additional analyte or non-analyte related signal. Such measurements may provide a background and/or sensitivity measurement(s) for use in processing sensor data and may be used to trigger events such as digital filtering of data or suspending display of data. The sensor can be advantageously designed to be integrally formed, including two electrodes E1, E2 embedded within an insulator I.
(FR)
La présente invention concerne des systèmes et procédés pour un capteur de substances à analyser en continu, comme un capteur continu de glucose. Un tel système utilise des première et seconde électrodes actives pour mesurer un signal additionnel relié à une substance à analyser ou à ne pas analyser. De telles mesures permettent de réaliser des mesures de fond et/ou de sensibilité utilisées dans le traitement de données de capteur et peuvent être utilisées pour déclencher des événements comme le filtrage numérique de données ou la suspension d'affichage de données. Le capteur peut être conçu de façon avantageuse pour être réalisé intégralement, y compris les deux électrodes E1, E2 incorporées dans un isolant I.
