German scientists combined information technology, micro-system technology and neuroscience to develop an artificial eye for the blind. The German Ministry of Science, Education and Research has just approved this plan and allocated 20 million marks for mass production of this kind of artificial eye.
This kind of artificial eye was developed by Professor Rolf Eckmiller from Bonn University and electronic scientists from Frankfurt College. The principle is: firstly, the picture shot by the camera is turned into an optical signal by a neural computer, then the coded picture is transmitted to a chip installed on the back wall of the retina by a laser, and the generated electric pulse is transmitted to nerve cells on the retina, and finally all the information on the picture is transmitted to the brain of the blind through the optic nerve. At this time, the blind can watch the pictures taken by the camera like normal people. The appearance of this kind of artificial eye will make the blind see the light of day again and feel the beauty of nature.
Digital hearing AIDS bring great convenience to patients with hearing loss, but they are of no help to deaf people who are completely deaf. At present, European and American countries have developed an artificial ear for the deaf. Putting this artificial ear into the cochlea of the deaf-mute can produce hearing. It is very complicated to make this kind of artificial ear, because for healthy people, it is only a matter of moments from a sound to the ear and then to the ear, but it involves 30 thousand nerve cells, and the artificial ear must imitate the structure of the human ear to have hearing function.
Due to various diseases or accidents, many people around the world lose their legs every day, and the demand for artificial limbs is increasing. European scientists are implementing a plan to "make you stand up". British scientists have developed a prosthetic limb that can make 1 a 34-year-old woman who lost her legs in a car accident stand for four minutes. Don't underestimate how hard these four minutes are for Julie Hill. The doctor placed six pairs of *** 12 electrodes on both sides of Julie Hill's spine, thus generating electric pulses of 12 to 15 per second to act on muscles and nerves. Julie Hill can start the program to control the electric pulse by pressing the button of the microcomputer. Once the receiver installed on her chest receives the instruction, the muscles begin to move. Of course, Julie Hill still needs crutches.
Professor Wolfgang Donich of the German Neurotherapy Center is developing an artificial walking system that allows patients to throw away crutches. His research object is paraplegic patients trapped in wheelchairs for life. Professor Donich is worried about the danger of doing experiments on patients. He used computer technology to design a virtual paraplegic patient and installed 180 muscles for him. He let one of the muscles move and carefully observed the influence of this muscle movement on other muscles and the whole body. On this basis, Doniher developed a robot named "Freddy" and connected it to a computer. With the help of the computer, "Freddie" stood up and stood firmly. Even if the golden rooster is independent, it will not fall, that is, it will be shaken by external force and still "stand still". 1in the summer of 996, Doniher made up his mind to do experiments on people. Several paraplegic patients are willing to take the test. Professor Doniher is going to let these patients throw away their crutches and get out of their wheelchairs with the help of artificial walking system.
The perfect combination of modern electronic technology and biotechnology makes it no longer a dream for the blind to see the light again, for the deaf to see the light again, and for the paralyzed to take the road of life again. With the rapid development of high technology, what will be presented to the disabled will be to recast the bright future of life.
