The world's first "bionic eye" is 46 times strong!

Produced | NetEase News

Introduction: The bionic technology of human organs has always been a hot spot in the field of research. "Bionic Eyes" is an important research topic for many scientists. Professor Fan Zhiyong, Hong Kong, my country, successfully developed a new generation of bionic eyes. The 460 million photosensitive components were 46 times that of human beings, which caused a global sensation, making "bionic eyes" a hot topic again.

First, where is the difficulty of bionic eyes?

In 1860, Darwin wrote to American botanist Assassor: So far, my eyes made me shudder, but when I thought of those who were known to be known, my rationality told myself that I must overcome this kind of shuddering Essence Initially single -cell biological vision originated from photoretically sensitive cells, which can achieve the decision of light or not. Later, marine life evolutionary and out of the scorched lens, which can adjust the visual system according to the distance, and then to the more complex eyeball structure of humans, you can perceive all each. Spectral spectrum forms a colorful visual world.

Eyes mainly include corneal, lens, vitreous, retina, and visual nerves, which show the spherical shape as a whole. External things are mapped to the retina through the corneal and lens. Among them, the crystal structure is similar to convex lenses, and the lens can adjust the focal length. The retina is similar to the light screen that receives images.

The retina is the most complicated structure of human eyes. It mainly includes photoretically sensitive cells, bipolar cells, and ganglia cells. In order, the light signal is transformed into a electrical signal, classified processing of electrical signals, and transmission of electrical signals. Among them, the retina is a hemisphere, which can achieve wide -angle receiving light.

2. How powerful is China's bionic eye?

1. Bionic eye hemispherical diaphragm technology

Hemisphere is a structure of bionic eye obtaining images, and is the core technology in bionic eyes. First of all, the retinal manufacturing is completed on the plane structure, and then folded into a spherical structure or directly into the spherical support material to form a similar visual wide-angle-150 ° -160 °. Secondly, the selection of metharide lead (FAPBI3) with superior optical performance is used as the material, which uses the gas deposition method to allow it to cause a physical chemical reaction in the gas state. Structure of supporting materials (PDMS Eye Socket). In addition, by controlling the distance between the light -sensitive nano wires, its density exceeds the density of the sensitivity cells in the retina of the human retina, which also realizes the ability of bionic eye resolution to exceed human eyes.

2. The liquid metal nerve fiber technology of bionic eye

The liquid metal nerve fiber can transmit an optoelectronics signal to the processing unit, which is a key technology in bionic eyes. In order to obtain sufficient resolution, the nerve fiber that needs to be as small as possible in the diameter of the diameter, the team of Chinese scientists develops a metal micro -needle structure of 1um2 with a cross -area of ​​1um2, breaking the effect of too large the diameter of the nerve fiber. This technology is my country's bionic eye eyes. Important breakthroughs. At the same time, China's bionic eye places nerve fibers on the back of the sensitivity material, so that it will not block the light, avoid weakening light and visual blind spots, and solve the problem of human nerve festival cells before sensitivity cells.

3. Optical treatment technology of bionic eyes

The lighting processing technology converts the light signal into a electrical signal, and its processing level will determine the response speed and stability of the bionic eye. First, the tungsten material is covered with the bionic front hemisphere (Al shell sclera), and a closed loop circuit is formed with the retinal rear ball. When the light is on the optical nano line, an ion signal will be generated, and the current signal will eventually generate. Secondly, the human eye signal can prioritize the spread of propagation through the photosensitive cells, bipolar cells, and then to the ganglia cells. The reaction is about 7 times the response speed of human eyes.

Third, what is the meaning of bionic eyes?

Compared with the plane retinal structure used by traditional bionic eyes, the latest bionic eye developed by my country can obtain a wider perspective and obtain a visual system closer to human visual effects. This technology is the biggest result of the bionic eye technology in recent decades. What does it mean?

1. Super AI robot

As an industry in the next air, AI robots have received widespread attention. The most famous is the Boston power robot. With its super control capabilities, it has achieved high flexible exercise capabilities, and its sports ability is far beyond humanity. The visual ability of the new generation of bionic eyes in my country can achieve the effect of transcending human visual ability. If the technology can be applied to AI robots, it will inevitably bring the effect of similar Boston robot sports performance, and achieve a new evolution in the resolution and response speed. It is far beyond the visual ability of human eyes and becomes a super AI robot. This is for AI robots to further enter human society, such as AI drivers, AI police, and AI doctors.

2. Patient visual medical treatment

Hundreds of millions of visual patients around the world have made these patients seeing light has always been a research topic for many scientists. my country's new generation of bionic eye provides better technical solutions, allowing patients to regain human visual ability and even beyond human visual level. By implanting the chip in the brain, the use of the brain interface technology, so that the bionic eye becomes part of the human body and exerts stronger visual ability. In the future, this technology will be carried out in animal experiments and continuously upgrades. Details will be successfully applied to medical care. By then, bionic eye technology will bring light to countless people. An important page of the history of human medicine. Medical Bionic Eye Application

3. Visual equipment

The new generation of bionic eye visual capabilities far exceeds the current mainstream visual equipment, which will achieve new development in many fields of visual equipment. For example, it is applied to autonomous vehicles to build a faster visual system, which can automatically identify in safety accidents, and take measures faster to achieve emergency avoidance functions to provide more secure intelligent driving techniques for humans; applied to aerospace; Camera, installed in an alien detector, adopts a compact structure and wide -view angle vision, can bring stronger visual detection to the aviation field; applied to the Yuan universe, so that humans can not only see the real world, but also enter the future Yuan universe. Let you switch freely in authenticity and virtual; apply to intelligent wearables, provide auxiliary visual support for human life and work, and enhance people's visual ability.

Bionic eye visual equipment application scenarios

Conclusion:

Human beings have evolved from primitive society to modern society, from unsatisfactory foods and uniforms to intelligent society, and scientific and technological progress has promoted human development. Maybe some people suspect that the future of bionic eyes is like the past human view of transportation tools. 20 In the 1950s, people must not be able to predict the development of automated driving today. Time is to verify the scale ruler of all technologies.

As stated in the Navarbao Book, "As a life system, everything we do is to promote the acceleration of the universe to achieve heat silence." Smart technology, bionic eye, will further subvert the concept of human beings and make the world system more complex. Perhaps it is human technology that allows us to further enter the ultimate realm of the universe.
