Revolutionary Contact Lens To See In The Dark

Celebrate; because soon you will be able to see at night! Researchers have developed a revolutionary sensor that helps to make the visible infrared spectrum, while the human eye is unable to distinguish the color spectrum at night. Objects such as contact lenses may be equipped with it to identify the colors during night. Really it is a so promising innovation for mankind.

Infrared imaging is generally associated with cumbersome and impractical equipment. With Graphene, a very compact layer of carbon atoms, researchers from the University of Michigan have developed a much more accessible sensor only need to be at room temperature to operate. Zhaohui Zhong, an assistant professor said that they can make this item very end and it can be incorporated into a contact lens. Scientists have detected light by observing how the electric charges in the graphene impact when current circulating therein.

They placed an insulating barrier between two graphene sheets and found that the electrons released when the light touched the top sheet, still came in their way to the bottom. When the researchers measured changes in current between the top layer and the bottom layer, they were able to determine the intensity of the light flash which reached graphene.

They invented a new way of detecting light and they already envision that people will be able to adopt this mechanism in many devices. This sensor, smaller than a little finger nail, could offer many advantages in the scientific and military communities, in addition to its potential to the general public.

Google has already announced in January the development of an intelligent contact lens that could monitor the level of glucose in our blood. In February, Nokia has received a grant of 980 million Euros from the European Union in order to design a type of graphene proved to be the strongest material in the world that is 300 times more than steel.

This innovative technology can really please us. We are delighted to learn that the infrared sensors could advance medicine but also equip ourselves with night vision. We hope that contact lenses or other devices will soon be equipped with these sensors to go play outside after dark.

A New Prototype Contact Lens To Stay Connected

Contact lenses with many features are no longer science fiction. A team of South Korean scientists has indeed developed a new prototype equipped with LED lenses that could display information directly and on our cornea. Find out what you may be in the near future.

Contact translucent lenses are not new: many use it on a daily basis to improve their eyesight, or just for aesthetic reasons. But scientific research has to go further with this technology. This is the case of a team of South Korean researchers from the National Institute of Science and Technology of Ulsan (UNIST) comes to design flexible contact lenses and equipped with LEDs.

One of the main issues concerning the transparent electrodes used in products such as mobile phone screens or those of television is that the material does not work if it is bent or simply folded. Hence it could not be used with contact lenses. Yet this successful team led by Jang- Ung Park made a lens composed of graphene layers alternating with layers of with others. Scientists have also shown that ILDED technology (inorganic LED diode) could easily fit on the surface of one of the lenses used in many applications, such as display pictures or videos directly in the eye.

For now, these contact lenses were tested on live rabbits which showed no sign of discomfort or irritation so far. Unfortunately for anyone hoping to have contact lenses that have the same functions as the eyes of the Terminator robot, the team of scientists said it is still far away. That said, we must not lose hope since the technology is constantly changing and this prototype lenses will certainly change a lot in the coming years. Sooner or later you could have the contents of a Smartphone directly in the eye.
