Инженерия Гарвард мектебі адаптивті metalinzy әзірледі — автоматты түрде фокустау және пайымдауы ақауларын реттеу жазық жасанды электрондық көз.

«Бұл зерттеу адам көз ретінде, нақты уақытта назарында өзгерту жасанды бұлшық metalinz технологиялармен серпінді технологияларды біріктіреді, — Алан Chez, ғылым жетістіктері журналына жарияланған қағаздың бірінші авторы дейді. — Біз қадам алға шығып, осындай адам көз қабілетті болып табылмайтын қандай имиджін астигматизм немесе ауыстыру сияқты қарқынды дұрыс ақаулар мүмкіндік берді «.
Әдетте металдың өлшемі өте аз, шамамен 100 микрон, ал берілген ақпараттың тығыздығы, керісінше, өте жоғары. Егер осындай линзаның өлшемін 1 см-ге дейін арттырсаңыз, онда деректер саны пропорционалды түрде өседі. Бұл мәселені шешу үшін ғалымдар жаңа өлшемді алгоритм жасап, диаметрі 1 см немесе одан көп болатын заманауи интегралды схемаларға сәйкес келуі үшін файл өлшемін азайтады.

Содан кейін ғалымдар металлды жасанды бұлшықпен байланыстырып, жарыққа назар аудару қабілетіне нашарлаған жоқ. Адам көзінде линза бұлшық бұлшықеттермен қоршалған, оны созып немесе қысқартады. Синтетикалық алмастырғыш ретінде кернеуді өзгерту арқылы басқарылатын мөлдір диэлектрлік эластомерлер таңдалды. Жасанды бұлшықеттердің төмендеуі металлдағы нанотүтіктерді ауыстыруды тудырады, нәтижесінде алынған кескін түзетіледі. Линзаның және бұлшықеттің қалыңдығы 30 микроннан аспайды.

Өнертабыс авторлары оған құқықтарды тіркеді және енді оны коммерциялық пайдалану жолын іздеуде, деп жазады EurekAlert.
Өткен жылдың қыркүйегінде Канадалық Ocumetics компаниясы линзаны алмастыратын бионды линзалардың клиникалық сынақтарын бастады. Объектив көзге имплантацияланып, көруді қалпына келтіріп, тым алыс немесе тым жақын заттарға назар аударуға мүмкіндік береді және көзіңізді шаршамайды.
