Abstract

La présente invention concerne un capteur électromagnétique (1) destiné à la détection de micro-déformations statiques et dynamiques comportant un élément ferromagnétique magnétoélastique (11), une bobine d'excitation (6) pour émettre un signal d'excitation vers l'élément ferromagnétique (11), une bobine de détection (7) pour la détection d'un premier signal émis par l'élément ferromagnétique (11) résultant du signal d'excitation. On peut améliorer un tel capteur en réalisant la connexion solide d'un élément d'aimant permanent (21) à un corps, dont on veut mesurer les déformations statiques et dynamiques. Un tel capteur peut être également amélioré par la réalisation d'une gaine (12) d'un matériau élastique pour l'élément ferromagnétique (11), montée de sorte que l'élément ferromagnétique (11) soit au moins partiellement encastré dans la gaine (12). L'invention concerne également un procédé de mesure de micro-déformations statiques et dynamiques.
