Un nouveau pansement high-tech d\u00e9velopp\u00e9 par des chercheurs de la North Carolina State University favorise activement la cicatrisation des plaies et peut \u00eatre activ\u00e9 tr\u00e8s simplement par une goutte d'eau. Celle-ci p\u00e9n\u00e8tre dans une couche de cellulose qui se trouve dans la batterie biocompatible \u00e0 la surface du pansement. La cellulose devient ainsi conductrice et la batterie commence \u00e0 produire de l'\u00e9lectricit\u00e9. Celui-ci circule entre deux \u00e9lectrodes situ\u00e9es sur la face inf\u00e9rieure du pansement et plac\u00e9es directement sur la plaie, de sorte qu'il passe \u00e0 travers. La tension est de 1,5 volt.<\/p>\n

Une flexibilit\u00e9 extr\u00eame<\/b><\/p>\n

Outre la possibilit\u00e9 d'activer la batterie par l'eau, le pansement pr\u00e9sente une autre particularit\u00e9 : tant les \u00e9lectrodes que la batterie sont extr\u00eamement flexibles, de sorte qu'elles s'adaptent id\u00e9alement \u00e0 la plaie et l'alimentent en \u00e9lectricit\u00e9 de mani\u00e8re optimale. En outre, selon les concepteurs, le pansement s'adapte aux mouvements de la personne dont la plaie doit gu\u00e9rir, de sorte qu'il ne g\u00eane pas au quotidien.<\/p>\n

Comme le pansement peut \u00eatre mis en place par les patients eux-m\u00eames, il y a de fortes chances qu'il soit utilis\u00e9 de mani\u00e8re continue. Selon le scientifique Rajaram Kaveti, qui fait partie de l'\u00e9quipe de d\u00e9veloppement, le pansement \u00e9vite aux gens de devoir se rendre \u00e0 l'h\u00f4pital pour changer leur pansement. La batterie suffit pour environ huit heures, apr\u00e8s quoi le pansement doit \u00eatre chang\u00e9.<\/p>\n

Cicatrisation plus rapide des plaies<\/b><\/p>\n

Les chercheurs ont test\u00e9 le pansement sur des souris diab\u00e9tiques souffrant de plaies chroniques. Il s'est av\u00e9r\u00e9 que l'\u00e9lectrostimulation acc\u00e9l\u00e9rait la gu\u00e9rison de 30 % en moyenne. \"Tout aussi important est le fait que ces pansements peuvent \u00eatre fabriqu\u00e9s \u00e0 un co\u00fbt relativement faible\", explique Bandodkar. \"On parle ici de quelques dollars par pansement\". Actuellement, le traitement des plaies chroniques chez les diab\u00e9tiques est tr\u00e8s co\u00fbteux et inefficace. Une fois qu'elles sont gu\u00e9ries et que le traitement est termin\u00e9, elles se rouvrent souvent. Dans les cas extr\u00eames, il faut m\u00eame amputer des parties du corps.<\/p>\n
