Title
(EN) SENSOR SYSTEM FOR SENSING ENVIRONMENTAL MOISTURE CHANGES, THE SENSOR SYSTEM COMPRISING A POLYMER MATRIX AND A PLURALITY OF CONDUCTIVE PARTICLES EMBEDDED WITHIN
(FR) SYSTÈME DE CAPTEUR DESTINÉ À DÉTECTER DES CHANGEMENTS D'HUMIDITÉ AMBIANTE, LE SYSTÈME DE CAPTEUR COMPRENANT UNE MATRICE POLYMÈRE ET UNE PLURALITÉ DE PARTICULES CONDUCTRICES NOYÉES À L'INTÉRIEUR DE CETTE DERNIÈRE
Abstract
(EN) A sensor comprises: an electrically comprises a switchable polymeric element. The polymeric element has at least a first electrical state and a second electrical state and is switchable between the first and second electrical states as a function of predefined environmental changes. The sensor comprises a polymeric matrix and a plurality of conductive particles embedded in the polymeric matrix.
(FR) La présente invention porte sur un capteur qui comprend un élément polymère apte à commuter électriquement. L'élément polymère présente au moins un premier état électrique et un second état électrique et est apte à passer entre les premier et second états électriques en fonction de changements environnementaux prédéfinis. Le capteur comprend une matrice polymère et une pluralité de particules conductrices noyées dans la matrice polymère.
