Abstract

L'invention concerne un circuit de collecte d'énergie (6) comprenant un circuit de syntonisation automatique permettant de rechercher une fréquence de radiodiffusion dans une bande d'intérêt et de ne sélectionner que les signaux de radiodiffusion reçus avec une puissance RF suffisante en vue d'une utilisation pour la collecte d'énergie. Ce circuit permet d'obtenir des dispositif de stockage d'énergie comprenant un circuit doté d'une unité destinée à sélectionner le signal RF ambiant pouvant maximiser ou augmenter la performance d'un circuit RFID par augmentation de la quantité d'énergie à collecter. Cette syntonisation automatique permet à un circuit de charge de dispositifs de stockage d'énergie de se déplacer d'un emplacement à l'autre sans syntonisation manuelle du circuit, et d'augmenter la plage efficace d'un circuit RFID.
