Abstract

L'invention concerne un dispositif et un procédé permettant de détecter la présence d'une matière dangereuse dans un environnement ou à travers un matériau d'essai, par exemple, un matériau de protection. Le dispositif peut comprendre un capteur destiné à détecter la présence de la matière dangereuse. En particulier, la matière dangereuse peut avoir une pression de vapeur inférieure à 0,5 mmHg. Le capteur contient un polymère conducteur, un polymère semi-conducteur ou un polymère électroactif, le capteur étant chimiquement réactif avec la matière dangereuse pour générer un changement de résistance électrique dans le capteur. Le dispositif peut comprendre une ou plusieurs électrodes conductrices fixées au capteur, conçues pour détecter un changement de résistance dans le capteur, et un dispositif de mesure de résistance connecté électroniquement à la ou aux électrodes pour recevoir des données provenant des électrodes et pour générer une sortie sur la base des données correspondant à une quantité de matière dangereuse détectée par le capteur en temps réel.
