Artificial eyes are eyeing the near future
It is indeed incredible how technology enthusiasts and scientists are paving the way for eye-opening innovations in the realms of technology. Not only does it intrigue our minds, but it allows us to decipher the science behind the eye-popping discovery. For instance, it is conjectured that the emergence of artificial eyes is likely to outperform human eyes one day. Isn’t it quite hard to believe?
Does it not let your brain’s motors ponder upon the said subject?
Yes, dear readers, the introduction of Eye Spy is likely to change the upcoming future. Let us read to learn more.
Eye-popping Eye Spy
Eye Spy is an artificially intelligent software designed or modeled in the form of a human eye. Indeed, it is an expected replica of an eyeball, and at the back of it lies a synthetic retina embedded with nanoscale light sensors. These sensors somewhat transmit the light through the lens in front of the eyes. In addition, the cords attached to the back of the retina ferry signals from sensors to external circuitry for processing, which is identical to the way nerve fibers are attached to the eyeball and the brain.
Fascinating facts about artificially intelligent eyes
The artificially intelligent eye is no less than a revelation in technology. In light of this, it can outperform and transcend the human eye one day. Let us look at how it can cast its spell on our understanding.
- The artificial eyeball records changes in light faster than human eyes can — within about 30 to 40 milliseconds, rather than 40 to 150 milliseconds.
- The device can also look at dim light as well as the human eye.
- Although its 100-degree field of view is not as broad as the 150 degrees a human eye can take in, it is better than the 70 degrees visible to ordinary flat imaging sensors.
- This synthetic eye could perceive a much higher resolution than the human eye because the artificial retina contains about 460 million light sensors per square centimeter.
EC- Eye: A technology prosthetic?
Researchers from the Hong Kong University of Science and Technology have developed an electrochemical artificial eye, called EC-Eye. Here, artificial eyes mimic the structure of a human eye, which could be a technological prosthetic or could even serve as a bionic eye for people suffering from visual impairment.
The Structure of EC-eye
- An aluminum-lined tungsten shell serves as the circular casing for the EC-Eye, which is filled with an ionic liquid.
- At the front, it has an iris and a lens, while at the back, it has a retina. The retina is made up of an aluminum oxide base with pores that each contain a photosensor.
- At the back of the retina, there are thin, flexible wires made of a liquid metal (eutectic gallium-indium alloy) wrapped in soft rubber tubes. The wires, which resemble nerve fibers that connect the human eye and brain, send signals from nanowire photosensors to external circuitry for processing.
- The electrical contact between the perovskite nanowires and the liquid-metal wires at the rear is improved by a coating of indium. A silicone polymer socket holds the artificial eye in place and ensures that the wires and nanowires are properly aligned.
- The EC-Eye could see with greater resolution than a human eye because the artificial retina has 460 million light sensors per square centimeter. Light-sensing cells in human retinas number roughly 10 million per square centimeter. This would, however, necessitate individual readings from each sensor.
Aside from aiding human vision, experts believe this research will aid in the development of other biomimetic photo-sensing devices that might be employed in a variety of technological applications.
