More Information
Summary:An RF power harvesting insert (100) for a wristwatch, the insert comprising a dielectric substrate (102) and an antenna (104) tuned to harvest power from RF electromagnetic fields to provide a radio frequency electrical signal and comprising a track of electrically conductive material on the substrate, wherein the antenna is carried by an annular region of a first surface of the substrate. L'invention porte sur un insert de récupération d'énergie RF (100) pour une montre-bracelet, l'insert comprenant un substrat diélectrique (102) et une antenne (104), accordée pour récupérer de l'énergie à partir de champs électromagnétiques RF afin de fournir un signal électrique radiofréquence (RF) et comprenant une piste de matériau électroconducteur sur le substrat, l'antenne étant portée par une région annulaire d'une première surface du substrat.
