Abstract

Dispositif de capteur de déplacement comprenant un circuit imprimé (24) comprenant plusieurs couches, et deux électrodes de mesure (31 , 32) disposées sur des faces externes du circuit imprimé (24) en vue de former deux condensateurs avec une électrode externe correspondante, les capacités des deux condensateurs variant de façon antagoniste de telle sorte qu'une mesure différentielle des deux capacités soit représentative du déplacement relatif entre les électrodes de mesure et les électrodes externes.
