Abstract

L'invention concerne un dispositif d'implant (32) réceptif à un circuit d'interrogation externe (38). Le dispositif d'implant (32) comprend une structure implantable dans un animal vivant (34) et conçue de manière fonctionnelle pour réaliser ou aider à la réalisation d'une fonction à l'intérieur de cet animal. Ce dispositif (32) comprend, en outre, un circuit passif de détection électrique (non représenté) solidaire à la structure destiné à détecter un paramètre associé à la fonction. Notamment, le circuit de détection (non représenté) comprend un élément inducteur (non représenté), et a sur le circuit d'interrogation (38) un effet de chargement d'impédance variable dépendant de la fréquence, en réponse à un signal d'interrogation produit par l'élément excitant/interrogateur (36), l'effet de chargement d'impédance variant en fonction du paramètre détecté.
