Abstract

La présente invention concerne un capteur de courant (10) pour détecter un courant (210) circulant dans un câble conducteur (200). Le capteur de courant (10) comprend une structure de capteur (100) comprenant une pluralité de capteurs magnétiques (122, 124). Chacun de la pluralité de capteurs magnétiques (122, 124) est disposé sur un substrat flexible (110) et comprend un axe de détection (123, 125). Le capteur de courant (10) comprend un câble conducteur (200) ayant un axe longitudinal et la structure de capteur (100) peut être au moins partiellement courbée autour du câble conducteur (200). La pluralité de capteurs magnétiques (122, 124) est disposée sur le substrat flexible (110) de sorte que lorsque le substrat flexible (110) est au moins partiellement courbé autour du câble conducteur (200), lesdits capteurs sont capables de détecter un courant électrique (210) circulant à travers le câble conducteur (200). La présente invention concerne également une structure de capteur (100) pour le capteur de courant (10).
