C’est une avanc\u00e9e neuro-proth\u00e9tique incroyable que vient de r\u00e9aliser l’Universit\u00e9 de Tel Aviv.<\/strong><\/em><\/p>\n

Par l’\u00e9quipe d’Unis avec Isra\u00ebl<\/em><\/p>\n

V\u00e9ritable perc\u00e9e m\u00e9dicale: des chercheurs de l’Universit\u00e9 de Tel Aviv ont r\u00e9ussi \u00e0 restaurer le sens du toucher \u00e0 des membres ayant subi de graves l\u00e9sions nerveuses.<\/p>\n

Un minuscule capteur implant\u00e9 dans le membre, comme un doigt par exemple, est connect\u00e9 \u00e0 un nerf sain.<\/p>\n

L’appareil se compose de deux petites plaques mesurant moins d’un demi-centim\u00e8tre sur un demi-centim\u00e8tre. Lorsque ces plaques entrent en contact les unes avec les autres, elles lib\u00e8rent une charge \u00e9lectrique qui est transmise au nerf non endommag\u00e9. Lorsque le doigt bless\u00e9 touche quelque chose, le toucher lib\u00e8re une tension correspondant \u00e0 la pression appliqu\u00e9e sur l’appareil \u2013 tension faible pour un toucher faible et tension forte pour un toucher fort \u2013 comme dans un sens normal du toucher.<\/p>\n

Les progr\u00e8s des neuro-proth\u00e8ses – des dispositifs qui restaurent les fonctions perdues \u00e0 cause des l\u00e9sions nerveuses – ont \u00e9t\u00e9 limit\u00e9s ces derni\u00e8res ann\u00e9es. Les appareils sont complexes \u00e0 produire et n\u00e9cessitent une source d’alimentation externe, telle qu’une batterie. Mais l’\u00e9quipe de l’Universit\u00e9 de Tel aviv a surmont\u00e9 ce probl\u00e8me redoutable en cr\u00e9ant un nanog\u00e9n\u00e9rateur tribo\u00e9lectrique (TENG) qui se charge lui-m\u00eame chaque fois qu’il d\u00e9tecte une friction.<\/p>\n

Les chercheurs expliquent que le capteur peut \u00eatre implant\u00e9 n’importe o\u00f9 dans le corps \u00e0 l’endroit o\u00f9 la sensation tactile doit \u00eatre restaur\u00e9e, et qu’il contourne en fait les organes sensoriels endommag\u00e9s. De plus, le dispositif est fabriqu\u00e9 \u00e0 partir d’un mat\u00e9riau biocompatible qui est s\u00fbr pour une utilisation dans le corps humain et simple \u00e0 implanter. Le capteur ne n\u00e9cessite pas d’entretien et n’est pas non plus visible de l’ext\u00e9rieur.<\/p>\n

Selon le Dr Ben Maoz de l’Universit\u00e9 de Tel Aviv, apr\u00e8s avoir test\u00e9 le nouveau capteur en laboratoire, les chercheurs l’ont implant\u00e9 dans les pieds des mod\u00e8les animaux. Les animaux marchaient normalement, sans avoir subi de l\u00e9sion de leurs nerfs moteurs, et les tests ont montr\u00e9 que le capteur leur permettait de r\u00e9pondre aux stimuli sensoriels.<\/p>\n

\u00ab\u00a0Nous avons test\u00e9 notre appareil sur des mod\u00e8les animaux, et les r\u00e9sultats ont \u00e9t\u00e9 tr\u00e8s encourageants\u00a0\u00bb<\/em>, a d\u00e9clar\u00e9 le Dr Maoz. \u00ab\u00a0Ensuite, nous voulons tester l’implant sur des mod\u00e8les plus grands et, \u00e0 un stade ult\u00e9rieur, implanter nos capteurs dans les doigts de personnes qui ont perdu la capacit\u00e9 de sentir le toucher. Restaurer cette capacit\u00e9 peut am\u00e9liorer consid\u00e9rablement le fonctionnement et la qualit\u00e9 de vie des personnes et, plus important encore, les prot\u00e9ger du danger. Les personnes d\u00e9pourvues de sensation tactile ne peuvent pas sentir si leur doigt est \u00e9cras\u00e9, br\u00fbl\u00e9 ou gel\u00e9. \u00bb<\/em><\/p>\n

L’\u00e9tude a \u00e9t\u00e9 publi\u00e9e dans la prestigieuse revue ACS Nano<\/em><\/p>\n
