terminator-style contact lens closer to reality  -  polyethylene terephthalate
Robots in the future should be careful: humans are using display technology to make computer contact lenses.
"Maybe one day we will be full.
There's mature streaming in your contact lenses, "said Babak Amir Parviz, associate professor of electrical engineering at the University of Washington.
In the latest issue of The Journal of micro-machinery and micro-engineering, a paper describing the new contact lenses of computer chemistry was written.

Parviz works with UW eye specialist Tueng Shen and researchers at the University of Alto, Finland, led by Markku Sopanen, professor of Optronics.
He said that Parviz's team is dedicated to integrating miniature devices into unconventional materials and has been working on functional contact lenses for a while.
"If we can make all kinds of very small devices, if we have the ability to put them into different materials, what can I do with the contact lenses I stare at every morning?
"The engineers accepted a very small customization --
The designed LED is made of sapphire and embedded in the center of the plastic contact lens.
They also embedded a circular antenna around the inner lip of the lens.
Micro integrated circuit connecting antenna and blue LED.
With remote RF transmission, the group is able to control individual pixels.
With this setting, the human eye still cannot distinguish the pixel due to the minimum focal length required to see anything clearly.
With this in mind, the researchers created a separate non-
A computerized invisible lens containing a special set of flat, thin lenses, called a Fresnel lens, each of which is less than micron thick.
The array successfully focuses on the light from the LED.
Once the researchers determined that the experimental lenses were safe in the lab, they tested them on live rabbits.
After wearing it for a short time, the rabbit did not have any scratches or heat burns.
"We have been able to build the whole system and test it on rabbits, on live eyes, to prove that it is effective and safe," Parviz said . ".
According to engineers, being able to display information and images directly into the field of view through contact lenses is useful in many ways.
These devices can be used for navigation, games, and even a way to monitor someone's health and safety.
This may also be a super sneaky way to access information while conducting a conversation.
This early system is still very rudimentary, says Parviz.
Computerized lenses are made of polyphenyl (PET)
A hard plastic that does not allow airflow to enter the eyes and is only allowed for a few minutes.
Although when the device is outside the eye, it can power from about 3 feet away, this distance is reduced to about inches when touching the actual eye.
Although the lighting of a single pixel may be useful as a warning, if there is no focus Micro
The rabbit saw only a vague shadow.
Researchers are planning to address these challenges.
They are trying to flatten the miniature
The lens technology of focusing light with computerized devices can be used in the laboratory.
They want to increase the number of pixels, improve the antenna design, expand the wireless range, and make components into softer, more flexible materials.
"If we can make them as comfortable as normal contact lenses, you don't feel like you're wearing them," Parviz said . ".
Contacts allow users to carry monitors, hands and headphones with them-free, he added.
"In a sense, it is the ultimate electronic device that is completely unobtrusive.
"News: nanotechnology may take advantage of your MindArnaud Bertsch, a microsystems researcher at the Lausanne Institute of Technology (EPFL)
In Switzerland, he has worked on integrating sensors into soft contact lenses for glaucoma testing.
The project led Sensimed, Switzerland, to sell a commercial product now.
"In order to have something that could be used as a device to project images onto the retina, there is more integration to be done, but basically the concept is here, and he talks about new contact lenses.
Bertsch believes that it may take 10 years to achieve a fully functional computer contact lens display, but added that with the help of micromation, the field has taken forward.
Five years ago, it was like science fiction.
"People are laughing when we start talking about integrating things into contact lenses," he said . ". "Now it's real.
