Title (EN) OPTICAL STRAIN SENSOR
(FR) CAPTEUR OPTIQUE DE DÉFORMATION
Abstract: front page image
(EN)The invention relates to use of an arrangement of a substrate and a liquid crystal layer provided on the substrate as an optical strain sensor, wherein the liquid crystal layer comprises liquid crystalline molecules having an ordered morphology and wherein the optical properties of the liquid crystal layer change by the strain of the substrate.
(FR)La présente invention concerne l'utilisation, comme capteur optique de contrainte, d'un agencement constitué d'un substrat sur lequel une couche de cristaux liquides est disposée. La couche de cristaux liquides comprend des molécules cristallines liquides à morphologie ordonnée et les propriétés optiques de la couche de cristaux liquides changent quand le substrat se déforme.
