What if you could be able to see at night! It sounds good right? Soon a new revolutionary contact lens loaded with stem cells which seem to be a regular lens will enable you to even see in the dark. Researchers have developed a revolutionary sensor, very promising innovation that can help you to see the infrared spectrum which is invisible by the naked human eye.
Current Infrared technology imaging is generally impractical equipment. This technology is used by doctors to monitor blood pressure and identify chemicals and now it also finds its application in equipment for seeing in the dark. Using the graphene, which is a compact layer of carbon atoms, researchers from the University of Michigan have developed a sensor which can operate at the normal room temperature.
Zhaohui Zhong, an assistant professor at the university said that we could make the sensor very thin as it can be incorporate in to the contact lens. Zhaohui placed an insulating barrier between two graphene sheets and found that the electrons were released when the light lies on the top of the sheet and these electrons were able to reach the bottom of the sheet. The researcher measures the changes in the both layers and they determine the intensity of the light to which the grapheme was wide open.
In January, Google has announced that the contact lens could monitor glucose levels in human blood. The lenses have yet to be tested on humans, but trials were made on animals established that they were able to see their way through obstacles in the dark. The main reason for this research is to help the blind people to read letters. Professor Zalevsky is also currently working on a similar sort of device to help people with hearing impairments.
The research is published in the journal Acta Biomaterialia. You would feel delight to know that infrared is not only used in medical applications but also enable us to view in nights.
