Engineers have created an LED display you can wear like a contact lens

Thanks to the advent of voguish phone technology , many of us already bear the cyberspace with us everywhere we go . But now , scientist have created the world ’s first wirelessly power , computerized contact lens with an integrated light-emitting diode display . That ’s right — the same memory access to information afforded us by the technology in our pockets could soon come to us via gadget that roost directly on our cornea .

The newfangled , functional contact lens come to us via the lab of Babak Amir Parviz , an electric engineer at the University of Washington . Parviz teamed up with UW ophthalmologist Tueng Shen , and a group of Finnish researchers led by optoelectronics prof Markku Sopanen , to create the novel video display technology , which is currently capable of lighting up a single blue picture element in reception to a wireless sign .

To create the computerized contact , the technologist plant a circular antenna along the rim of the lens , and coupled it with a tiny LED via an incorporate circuit . Using distant radio frequency transmission , the researchers can insure the activity of the single pixel , which is situated at the center of the lens .

The top effigy feature here shows the three main factor embedded in the lens . The investigator have already quiz the machine ’s safety on springy rabbits , also pictured here . Their results indicate that the brute suffered no abrasion from the plastic or burning from the lens ’ LED or wireless circuitry . Having said that , there are a number of obstacle that need to be master before you ’ll be able to stream Netflix straight to your eyeball , or google your day of the month while engaging them in dinner conversation .

For one thing , the lens in its present design is made from a knockout plastic that restrain air flow to the eye , which would forestall you from wearing the lens for more than a few minute at a prison term . The other major hurdle is accounting for your middle ’s minimal focal aloofness — i.e. the challenge of making any pixels that appear on the contact crystalline lens intelligibly seeable to your heart . ( The investigator claim to have get the better of this obstruction with a genus Lens contain exceedingly thin “ micro - Fresnel ” lenses that can focus the light from the LED over an incredibly lowly space . This limited pattern would , in theory , countenance your retina to pick up meaningful information from the crystalline lens and any information it might exhibit on your personal head - up display of the hereafter . )

And while you certainly ca n’t reckon much more than a message in morse code via a single - pixel interface , Parviz and his colleagues claim to already be moving toward a multipixel middleman - lens display that could one day allow you to ascertain the family relationship position of someone across the cake from you organize your inbox or check your missed calls — all from a tiny display rest neatly on your eyeball .

“ If we can make them as comfortable as normal physical contact lenses , you do n’t sense you ’re wearing them , ” Parviz says . He go forward :

If we can make very minor equipment of various sorts , if we have the ability to put them into different material , what can I do with this contact lens that I stare at every morning ? In a sentience , it ’s the ultimate electronic gear that is altogether unnoticeable .

The researchers describe their computerized physical contact lens in the late issue of theJournal of Micromechanics and Microengineering(no subscription required ) .
