CA 2752573

Described herein are improved configurations for a wireless power transfer for electronic devices that include at least one source magnetic resonator including a capacitively- loaded conducting loop coupled to a power source and configured to generate an oscillating magnetic field and at least one device magnetic resonator, distal from said source resonators, comprising a capacitively-loaded conducting loop configured to convert said oscillating magnetic fields into electrical energy, wherein at least one said resonator has a keep-out zone around the resonator that surrounds the resonator with a layer of non-lossy material.

La présente invention concerne des configurations améliorées pour un transfert d'énergie sans fil, pour des dispositifs électroniques. Les configurations comprennent au moins un résonateur magnétique de source comprenant une boucle conductrice à charge capacitive couplée à une source d'énergie et configurée pour générer un champ magnétique oscillant, et au moins un résonateur magnétique de dispositif, éloigné desdits résonateurs de source, comportant une boucle conductrice à charge capacitive configurée pour convertir lesdits champs magnétiques oscillants en énergie électrique. Ledit ou lesdits résonateurs possèdent une zone d'exclusion autour du résonateur qui entoure ce dernier d'une couche d'un matériau sans perte.
