Abstract

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.
