Abstract
Un capteur 10 destiné à mesurer la pression du liquide céphalo-rachidien à l'intérieur du crâne d'un patient comprend notamment un soufflet 16 dont la longueur varie en fonction de la pression mesurée, ce qui déplace un noyau 38 et modifie l'inductance d'une bobine 36 qui fait partie d'un circuit résonnant. On mesure la fréquence de résonance de ce circuit résonnant, et donc la pression, à l'aide d'un ondemètre qui est placé en couplage inductif avec la bobine.
