Abstract[English]
A strain characterization system (300) includes a strain sensor (100) having first and second electrodes (110, 120) that sandwich a dielectric layer (130) to form a capacitor; a power source (310) configured to inject a signal VAC between the first and second electrodes (110, 120) of the strain sensor (100); and a controller (312) configured to control the power source (310) and to select a frequency of the power source (310). The controller (312) is configured to select first to third different frequencies for determining a strain magnitude, a strain location, and an extent of a strain area.[French]
L'invention concerne un système de caractérisation de contrainte (300) comprenant un capteur de contrainte (100) ayant des première et seconde électrodes (110, 120) qui prennent en sandwich une couche diélectrique (130) pour former un condensateur ; une source d'alimentation (310) conçue pour injecter un signal VAC entre les première et seconde électrodes (110, 120) du capteur de contrainte (100) ; et un dispositif de commande (312) conçu pour commander la source d'alimentation (310) et pour sélectionner une fréquence de la source d'alimentation (310). Le dispositif de commande (312) est conçu pour sélectionner des première à troisième fréquences différentes pour déterminer une amplitude de contrainte, un emplacement de contrainte et une étendue d'une zone de contrainte.
