3D printer will LED screen implanted contact lenses

According to foreign media reports, University of Washington researchers announced that they are studying new technology: with built-in display of contact lenses.

Currently, this contact lens is only in the embryonic stage, can only display a single pixel information. But the researchers said that this contact lenses in the future and Google glasses, you can display more data and information, including e-mail. The contact lens is only 0.33 mm in diameter.

In order to make such a miniature device, including the display screen, and put all the parts perfectly placed on tiny polymer materials, the researchers used the 3D quantum cluster LED printer. The 3D printer can print different layers of interactive materials, each material has its specific purpose, in which a special radioactive layer collection material with quantum particles and electronic materials nanocrystals. According to the International Journal of Journal of Micromechanics and published in Microengineering research report shows that the quantum particle distribution between the release of electrons in a film layer and a layer of electron accepting film, which makes the photonic quantum particles release specific wavelength and color.

Quantum particles will produce a color screen through the film, the naked eye can see. This contact lens through the built-in antenna to gather energy, through the integrated circuit to store energy and energy transfer to a blue chip containing LED.

Finally, the cost of $20 thousand (about 122925 yuan) 3D printer will print out all the components and integration, through UV activated adhesive film, the production of real contact lenses. Although the technology used in the touch screen display sounds fantastic, don't get too excited because it's too expensive to produce in large quantities.

In addition, University of Washington researchers are not the first team to study smart contact lenses. Scientists at the University of Oxford is currently in the development of a nano pixel lens, while Amazon and Google have is developing a smart glasses consumer adapter version of the project team.
