Abstract

Cette invention a trait à une technique et à l'appareil correspondant permettant de déterminer de manière non effractive le taux de glucose dans les liquides organiques d'un sujet et, notamment, le taux de glucose sanguin. On mesure l'impédance du tissu cutané et l'on utilise cette mesure avec des mesures d'impédance précédemment mises en corrélation avec des taux de glucose directement établis, ce qui permet de déterminer le taux de glucose à partir de l'impédance venant d'être mesurée. Il est, de ce fait, possible de déterminer des taux de glucose d'un liquide de manière non effractive et routinière.
