Noi tehnologii: Wireless prin corpul uman.
\nCercet\u0103torii de la Washington au dezvoltat o nou\u0103 tehnic\u0103 de comunicare wireless, care trimite semnale magnetice direct prin corpul uman, un pas \u00eenainte care poate conduce la dezvoltarea produselor de tip wearables cu un consum redus de energie.
\nNoile tehnologii ar putea oferi un consum mai redus de energie \u0219i un mod mai sigur de comunicare \u00eentre echipamentele electronice de tip wearable, furniz\u00e2nd o alternativ\u0103 mai bun\u0103 la sistemele actuale de comunica\u021bii.
\nO prim\u0103 aplicabilitate a acestei tehnologii ar fi o re\u021bea de senzori wireless pentru monitorizarea st\u0103rii de s\u0103n\u0103tate a corpului uman.
\n\u201cPe viitor oamenii vor purta tot mai multe echipamente electronice, precum ceasurile inteligente, aparatele de monitorizare pentru activit\u0103\u021bile sportive si pentru s\u0103n\u0103tate\u201d a declarat Patrick Mercier, profesor \u00een cadrul Departamentului de Inginerie \u0219i Computere al Universit\u0103\u021bii din California, San Diego, care a condus studiul.
\n\u201e\u00cen momentul de fa\u021b\u0103 aceste dispozitive transmit informa\u021bii prin tehnologia radio Bluetooth, care folose\u0219te mult\u0103 energie electric\u0103 pentru a comunica fluxurile de date. Noi \u00eencerc\u0103m s\u0103 g\u0103sim noi modalit\u0103\u021bi de comunicare a informa\u021biei prin intermediul corpului uman, pentru a folosi mult mai pu\u021bin\u0103 energie\u201d a mai spus Mercier.
\nTehnologia Bluetooth folose\u0219te unde electromagnetice pentru transmiterea datelor, totu\u0219i aceste semnale radio nu trec u\u0219or prin corpul uman \u0219i de aceea necesit\u0103 un plus de energie pentru a dep\u0103\u0219i acest obstacol sau \u201cpierdere de semnal\u201d.
\nCercet\u0103torii au utilizat \u00een cadrul studiului o tehnic\u0103 denumit\u0103 \u201ccomunicare prin intermediul c\u00e2mpului magnetic al corpului uman\u201d, care se folose\u0219te de corpul uman ca de un element de leg\u0103tur\u0103 pentru a livra energie magnetic\u0103 \u00eentre echipamente electronice.
\nUn avantaj al acestui sistem este acela c\u0103 un c\u00e2mp magnetic poate trece liber prin \u021besuturile biologice, deci datele sunt comunicate cu o pierdere de semnal mult mai mic\u0103 \u0219i, poten\u021bial, cu un consum mult mai redus de energie.
\nCercet\u0103torii au demonstrat c\u0103 pierderea de semnal asociat\u0103 comunicatiilor prin c\u00e2mpului magnetic al corpului uman este de cel pu\u021bin 10 milioane de ori mai redus\u0103 dec\u00e2t cea prin unde radio Bluetooth.
\n\u201eDup\u0103 informa\u021biile noastre, aceast\u0103 tehnic\u0103 realizeaz\u0103 cea mai mic\u0103 pierdere de semnal la transmiterea datelor prin corpul uman fa\u021b\u0103 de orice alt sistem folosit p\u00e2n\u0103 acum. Aceast\u0103 tehnic\u0103 ne va permite s\u0103 dezvolt\u0103m echipamente mobile cu un consum mult mai redus de energie\u201d a mai spus Mercier.
\nCercet\u0103torii au men\u021bionat faptul c\u0103 aceast\u0103 tehnic\u0103 nu pune niciun fel de probleme de s\u0103n\u0103tate. Energia de transmitere a semnalelor electrice prin corpul uman este de c\u00e2teva ori mai redus\u0103 dec\u00e2t aceea a scanerelor cu rezonan\u021b\u0103 magnetic\u0103 sau cea a implanturilor cu transmitere wireless.
\nDe asemenea transmiterea datelor prin intermediul c\u00e2mpului magnetic uman ar putea oferi mai mult\u0103 siguran\u021b\u0103, dup\u0103 cum au spus cercet\u0103torii.
\nA fost construit un prototip pentru demonstrarea acestei tehnici de comunica\u021bii. Acesta const\u0103 \u00eentr-o re\u021bea de fire de cupru, izolate cu tuburi PVC. La un cap\u0103t firele de cupru sunt conectate la un analizor extern, iar la cel\u0103lalt cap\u0103t firele sunt \u00eenf\u0103\u0219urate sub form\u0103 de bobine \u00een jurul a trei zone ale corpului uman: capul, bra\u021bele \u0219i picioarele.
\nAceste bobine folosesc drept surse pentru c\u00e2mpul magnetic \u0219i pot trimite semnale magnetice dintr-o zon\u0103 \u00een alta a corpului.
\nCu acest prototip cercet\u0103torii au putut demonstra \u0219i m\u0103sura pierderea foarte mic\u0103 de semnal de la un bra\u021b la altul, de la bra\u021be la cap \u0219i de la bra\u021be la picioare.<\/p>\n","protected":false},"excerpt":{"rendered":"
