Monolayer- and compact-multilayer-stacked ingestible TX coils are investigated for ingestible capsule systems. The inductive link through the human body is modeled. The efficiency of the near-field magnetic induction link budget is evaluated in the air, in the homogeneous human body and in the three-layer human body. The variations of the position and the orientation of the TX capsule coil are taken into account to evaluate the coupling response between the TX ingestible and RX on-body coils.

Des boucles monocouches et multicouches compactes sont étudiées pour des systèmes de gélules ingérables. Le lien inductif à travers le corps humain est modélisé. L'efficacité du bilan de liaison en champ proche par induction magnétique est évalué dans l'air, dans le corps humain homogène et dans le corps humain trois couches. Les variations de la position et de l'orientation de la boucle dans la gélule d'émission sont prises en compte pour évaluer la réponse de couplage entre les boucles d'émission dans la gélule ingérable et de réception sur le corps humain.
