Title
(EN) LAYERED SENSORS AND METHODS OF USING
(FR) CAPTEURS STRATIFIÉS ET PROCÉDÉS D'UTILISATION
Abstract
(EN)
Layered implantable sensors are described herein. Layered sensors described herein may include one or more analyte sensing populations. The one or more analyte sensing populations may detect different analytes, or different concentrations of the same analyte, for example. The layered sensors may include a reference population. The reference population may, or may not, be analyte sensing. As described herein, the first sensing population may be separated from a second sensing population (and/or a reference population) by a passive layer.
(FR)
L'invention concerne des capteurs stratifiés implantables. Les capteurs stratifiés selon l'invention peuvent comprendre une ou plusieurs populations de détection d'analytes. La ou les populations de détection d'analytes peuvent détecter différents analytes, ou différentes concentrations du même analyte, par exemple. Les capteurs stratifiés peuvent comprendre une population de référence. La population de référence peut être, ou ne pas être, une population de détection d'analytes. Selon l'invention, la première population de détection peut être séparée d'une seconde population de détection (et/ou d'une population de référence) par une couche passive.
