De la taille d’un grain de sable, ce minuscule a\u00e9ronef permettra de transporter des capteurs pour surveiller l’environnement.<\/strong><\/p>\n\n\n\n

Voici le\u00a0microflier, il s’agit de la plus petite machine volante que l’Homme a cr\u00e9\u00e9e. <\/p>\n\n\n\n

De la taille d’un grain de\u00a0sable, cette invention issue des laboratoires de l’Universit\u00e9 Northwestern aux \u00c9tats-Unis, est con\u00e7ue pour collecter et transmettre des donn\u00e9es environnementales durant son vol. <\/p>\n\n\n\n

Des micropuces ail\u00e9es reposent sur une structure dot\u00e9e de trois ailettes en forme d’h\u00e9lices.<\/p>\n\n\n\n

Son faible poids et les ailettes lui permettent, une fois lanc\u00e9\u00a0en l’air, de se faire porter par le\u00a0vent\u00a0comme les\u00a0aigrettes\u00a0d’un\u00a0pissenlit, avant de retomber tr\u00e8s lentement. Cette longue chute lui donne le temps n\u00e9cessaire pour\u00a0la collecte de donn\u00e9es. Des donn\u00e9es qui sont relev\u00e9es par des microcapteurs et qui servent \u00e0 \u00e9valuer la\u00a0qualit\u00e9 de l\u2019air, relever la pr\u00e9sence de\u00a0virus\u00a0ou encore de contaminants dans celle-ci.<\/p>\n\n\n\n

Des puces biod\u00e9gradables<\/h2>\n\n\n\n

En plus des\u00a0capteurs, les micropuces\u00a0peuvent \u00e9galement transporter un petit \u00e9metteur et m\u00eame stocker des donn\u00e9es. C’est encore une fois en\u00a0s\u2019inspirant\u00a0de la nature que les scientifiques sont parvenus \u00e0 cr\u00e9er ce minuscule\u00a0a\u00e9ronef. Leur mod\u00e8le repose sur les graines de la tristellateia, une plante grimpante, dont les fruits en forme d’\u00e9toile\u00a0sont des capsules avec des ailes. Cette structure permet aux graines de voyager et de retomber au sol tr\u00e8s doucement.<\/p>\n\n\n\n

Et ce n’est pas tout, puisque dans l’avenir, ces microfliers pourraient bien \u00eatre de surcro\u00eet\u00a0biod\u00e9gradables. Les chercheurs, qui ont publi\u00e9\u00a0leurs travaux dans la revue\u00a0Nature<\/em>, planchent en effet sur l’utilisation de mat\u00e9riaux capables de se dissoudre au sol ou dans l’eau, une fois leur mission accomplie.<\/p>\n\n\n\n
