Il existe un \u00e9norme potentiel de croissance dans le secteur des \u00e9quipements portables, qui devrait atteindre une valeur de march\u00e9 de 72 milliards d\u2019euros d\u2019ici 2020.<\/p>\n

Les trois batteries segment\u00e9es du bracelet ont chacune une capacit\u00e9 de 300 mAh, une capacit\u00e9 de stockage de 1,1 Wh et une perte de moins de trois pour cent de leur capacit\u00e9 de charge par an. Cela suffit pour alimenter une montre intelligente conventionnelle sans perte d’ex\u00e9cution. Le prototype bat des produits bien \u00e9tablis, tels que les montres intelligentes, dans lesquelles la pile est uniquement int\u00e9gr\u00e9e au bo\u00eetier de la montre et non au bracelet.<\/p>\n

\u00abSi vous rendez une batterie extr\u00eamement flexible, sa densit\u00e9 \u00e9nerg\u00e9tique sera tr\u00e8s faible. Il est donc pr\u00e9f\u00e9rable d\u2019adopter une approche segment\u00e9e\u00bb, a d\u00e9clar\u00e9 Robert Hahn, chercheur au sein du d\u00e9partement Fraunhofer IZM pour les syst\u00e8mes de capteurs RF et intelligents.<\/p>\n

Au lieu de rendre les batteries extr\u00eamement flexibles au d\u00e9triment de la densit\u00e9 \u00e9nerg\u00e9tique et de la fiabilit\u00e9, l’institut s’est concentr\u00e9 sur la conception de batteries tr\u00e8s petites et puissantes et a optimis\u00e9 la technologie de montage afin que les batteries soient flexibles entre les segments. Cela permet \u00e0 la bande intelligente d’\u00eatre flexible tout en conservant beaucoup plus de puissance que les autres bracelets intelligents disponibles sur le march\u00e9.<\/p>\n
