Researchers are improving contact lenses advantage of vision in the dark

University researchers have developed a " Michigan " American sensor infrared can be used in the

production of contact lenses fitted with night-vision feature .

The researchers explained that the sensor can distinguish between different chemicals in low-light conditions , so as to permit the vision in the dark if they are combined with lenses of " graphene " , or put it on special cameras for mobile phones .

The researchers added that the lenses used with the sensor chips , sticks out of " graphene " , a substance derived from the two-dimensional carbon , which are chips that enhance the ability of the night vision lenses , and the distinction between things , at normal room temperature .

For his part , noted Zhao Hui Chung , an assistant professor at the University of " Michigan " , that night vision occur due to the sensitivity of the underlying electrical charges within the material graphene to light, especially at normal room temperature .

The research team has demonstrated the effectiveness of the sensor and lenses in a scientific way , after they came Blouhan of " graphene " and put the insulator of light between them , and noticed the movement of electrons when exposed to light and when blocked it, then took advantage of the movement of electrons that in determining Kevifah exploitation chips " graphene " with lenses to distinguish things in the dark .

This , Chung stressed that the new sensor , which is smaller in size than the size of a fingernail pinky finger , it can be used , in addition to the lenses " graphene " , in many applications , both in the scientific community or military operations or in the electronics industry.

It is noteworthy that most of the global company is currently working on the adaptation of " graphene " for the manufacture of consumer devices , where the company " Nokia " has got to $ 1.35 billion from the European Union in order to develop the material , which is the strongest in the year.

It should be noted that the " Samsung " has a few days ago to reveal a way to adapt the material " graphene " for use in the manufacturing process of electronic devices, especially in the semiconductor industry through the use of micro- chips " graphene " instead of chips " silicon " .
