Abstract[English]
Presented herein are techniques for charging a battery within an implantable component (implant) in a manner that optimizes (e.g., maximizes, increases) recharging efficiency while ensuring compliance with applicable regulatory safety limits. More specifically, presented herein is an inductive wireless power transmitter (WPT) that includes at least two drivers and at least two overlapping flat spiral coils configured to normalize the specific absorption rate (SAR) of human exposure to the generated electromagnetic (EM)/radio-frequency (RF) fields.[French]
La présente invention concerne des techniques permettant de charger une batterie dans un composant implantable (implant) de manière à optimiser (par exemple maximiser, augmenter) l'efficacité de la recharge tout en garantissant le respect des limites de sécurité réglementaires applicables. Plus précisément, le présent document décrit un émetteur d'énergie inductif sans fil (WPT) qui comprend au moins deux circuits d'attaque et au moins deux bobines hélicoïdales plates qui se chevauchent, configurées pour normaliser le débit d'absorption spécifique (SAR) de l'exposition humaine aux champs électromagnétiques (EM)/radiofréquences (RF) générés.
