Implantable Tx–Rx wireless systems. An overview of their efficiency analysis through scattering matrix formalism
Comptes Rendus. Physique, Online first (2024), pp. 1-18.

Looking at wireless implantable systems as a pair of or more Tx–Rx components, we discuss how their efficiency can be calculated in order to achieve an optimum result that can be evaluated over measurements and literature. To that end, scattering parameters’ notation is introduced instead of considerations of the gain, the propagation losses and the radiation patterns. Looking at the system as a black box, remarks on optimum link calculation in relation to frequency, antenna size, phantom use, matching circuit integration and efficiency intensifiers are being carried out. International standards for allowed power and safety levels are added to the discussion. Different scenarios including telemetry, wireless harvesting and sensor transmission information are included as examples.

En considérant un système implantable sans contact comme une paire de composants Tx–Rx (émetteur-récepteur), l’article montre que l’efficacité de transfert peut être calculée en vue d’obtenir un résultat optimal pouvant être évalué au moyen de mesures ou de résultats issus de la littérature. À cette fin, le formalisme des paramètres S (matrice de diffusion) est introduit à la place des quantités généralement utilisées (gain, pertes, diagramme de rayonnement). En considérant le système comme une boîte noire, des remarques sur le calcul de la liaison optimale sont formulées selon la fréquence, la taille de l’antenne, l’utilisation d’un fantôme, l’intégration de circuits d’adaptation et d’amplificateurs d’efficacité. Les normes internationales relatives à la puissance autorisée et aux niveaux de sécurité à respecter sont inclues dans la discussion. Différents scénarios incluant la télémétrie, la récupération d’énergie sans fil et la transmission d’informations par des capteurs sont présentés à titre d’exemples.
