Title (EN) SENSOR INTERROGATION WITH FAST RECOVERY
(FR) INTERROGATION DE CAPTEUR À RÉCUPÉRATION RAPIDE
Abstract:
(EN) A method of operating a sensor to detect an analyte in an environment, wherein the sensor includes a working electrode and circuitry in operative connection with the working electrode, includes performing a sensor interrogation cycle including applying electrical energy to the working electrode to generate a non-faradaic current, measuring a response to the generation of the non-faradaic current to determine a state of the sensor, and actively controlling the circuitry to dissipate the non-faradaic current.
(FR) Un procédé d'utilisation d'un capteur permettant de détecter un analyte dans un environnement, le capteur comprenant une électrode à étudier et un ensemble de circuits en liaison fonctionnelle avec l'électrode à étudier, consiste à effectuer un cycle d'interrogation de capteur comprenant l'application d'énergie électrique à l'électrode à étudier pour générer un courant non faradique, à mesurer une réponse à la génération du courant non faradique pour déterminer un état du capteur, et à commander activement l'ensemble de circuits pour dissiper le courant non faradique.
