Abstract

Un aspect de la présente invention concerne un dispositif qui détermine de manière non invasive la concentration d'une substance dans une cible. Ce dispositif comprend une première électrode, un circuit de mesure et un système de traitement des données. Dans un mode de réalisation de ce dispositif, la première électrode peut être électriquement isolée de la cible, par exemple au moyen d'une couche de revêtement en matériau isolant qui recouvre la première électrode.
