Abstract

Les communications sans fil dans des milieux à perte suscitent un intérêt croissant notamment dans des applications telles que la télémédecine, la détection d'un défaut de masse, la télédétection dans des canalisations et le contrôle de la qualité des aliments. En guise d'application, l'invention concerne un nœud capteur corporel (BSN) implantable autonome destiné à contrôler des paramètres physiologiques ou à commander des dispositifs thérapeutiques. Le système est miniaturisé et a été doté d'une forme cylindrique de façon à permettre son implantation dans le patient avec effraction minimale. Le système peut contenir un ou plusieurs dispositifs de détection ou composants électroniques autonomes nécessaires à la commande d'un dispositif thérapeutique. Il comporte un ou plusieurs étages d'entrée analogiques ou numériques permettant d'établir une interface avec un type quelconque de capteur ou de dispositif thérapeutique ou de commander celui-ci, un microcontrôleur programmable ou un processeur de signal numérique, une ou plusieurs batteries secondaires ou primaires, un éventuel mécanisme de recharge de batterie(s), un dispositif de télémesure radiofréquence compatible avec la bande du service de radiocommunications des dispositifs médicaux (MedRadio), un boîtier biocompatible étanche présentant une forme ergonomique et un mécanisme d'ancrage empêchant la rotation ou la migration du dispositif, et un module de commande externe. Les dimensions hors-tout du nœud capteur corporel peuvent varier en fonction de la puissance consommée par l'application et de ses capacités de recharge, mais également des dimensions de l'interface avec le capteur ou le dispositif thérapeutique. Plusieurs nœuds mis en réseau peuvent communiquer et échanger des informations avec le module de commande externe et donner lieu à des schémas d'applications biologiques complexes.
