Title
(EN) SENSORS BASED ON NANO-STRUCTURED COMPOSITE FILMS
(FR) CAPTEURS A BASE DE FILMS COMPOSITES NANO-STRUCTURES
Abstract
(EN) An electrically reactive composite article (20) comprising a random or regular array of microstructures (16) partially encapsulated within an encapsulating layer (12), microstructures (16) each comprising a whisker-like structure (14), optionally having a conformal coating (13) enveloping the whisker-like structure (14) is described. The composite article (20) is useful as an electrically conducting component of a circuit, antenna, microelectrode, reactive heater, and multimode sensor to detect the presence of vapors, gases, or liquid analytes.
(FR) Article composite électriquement réactif (20) comprenant un réseau aléatoire ou régulier de micro-structures (16) partiellement encapsulées à l'intérieur d'une couche d'encapsulation (12), ces micro-structures (16) renfermant chacune une structure en forme de trichite (14), présentant éventuellement un revêtement conformé (13) enveloppant ladite structure (14). Cet article composite (20) est utile comme composant électroconducteur d'un circuit, d'une antenne, d'une microélectrode, d'un dispositif de chauffage réactif, et d'un capteur multimode pour détecter la présence de vapeurs, gaz ou analytes liquides.
