Title
(EN) SYSTEMS AND METHODS FOR DETECTING A HEALTH CONDITION
(FR) SYSTÈMES ET MÉTHODES DE DÉTECTION D'UN ÉTAT DE SANTÉ
Abstract
(EN)
Embodiments herein include a method for detecting a health condition of a subject. The method can include obtaining a biological sample from the subject and placing it into a container having a headspace surrounding the biological sample. The method can include contacting a gas from the headspace with a chemical sensor element, the chemical sensor element including one or more discrete graphene varactors. The method can include sensing and storing capacitance of the discrete graphene varactors to obtain a sample data set. Other embodiments are also included herein.

Des modes de réalisation de la présente invention comprennent une méthode de détection de l'état de santé d'un sujet. Le procédé peut consister à obtenir un échantillon biologique du sujet et à le placer dans un récipient laissant un espace libre entourant l'échantillon biologique. Le procédé peut comprendre la mise en contact d'un gaz contenu dans l'espace libre avec un élément de capteur chimique, l'élément de capteur chimique comprenant un ou plusieurs varactors de graphène distincts. Le procédé peut comprendre la détection et le stockage de la capacitance des varactors en graphène distincts pour obtenir un ensemble de données d'échantillon. La présente invention concerne en outre d'autres modes de réalisation.
