There are often such bridges in the sci-fi blockbusters. The protagonist implants the chip to transform the body, and finally gains super power and becomes omnipotent. For most ordinary people, human implanted chips are like black technology that is out of reach. Recently, Li Xueling, co-founder, chairman and CEO of Happy Age (YY), exposed his body implanted chips in the WeChat circle of friends. This news makes people feel that this black technology seems to be far from reality.
Although the final result shows that Li Xueling uses only a blood glucose monitoring device, it is not a chip implanted in the body, but the topic of human implanted chips has once again caused heated discussion.
The medical field has long been applied
The practice of implanting chips into the human body is nothing new in the medical world. Implantable heart monitors are the outstanding representatives of human body chips in medical practice. The implantable heart monitor is only half the size of a chewing gum. It doesn't matter if it is small, it can make a big difference. When a cardiac event such as arrhythmia occurs, it can be detected in time and accurately, providing clinicians with reliable diagnostic evidence, and building a first line of defense against sudden cardiac death in patients with chronic cardiovascular and cerebrovascular diseases.
As early as September 2015, the Chinese Academy of Medical Sciences Fuwai Hospital successfully injected a heart monitor into the patient's body by injection. The implantation process is like inserting a tracking chip into the body in a movie block. A small opening of about 1 cm is cut subcutaneously in the chest, and an implantable cardiac monitor (ICM) is inserted subcutaneously into the left chest by injection. This technology can be widely used in the screening of clinically unexplained syncope patients, screening for paroxysmal atrial fibrillation in patients with unexplained stroke.
In addition to its widespread use in cardiology, human implantable chip technology will also change the traditional blood collection method for blood tests. Most people have experience in collecting blood in hospitals. The slender needles and the plastic hoses that turn red from white are the shadows of many people. Swiss scientists are studying subcutaneous implantable blood tests, as the name suggests, the entire blood test process is carried out under the skin. The subject only needs to implant a tiny blood test chip under the skin to detect the content of up to five proteins and organic acids in the blood.
In addition to protecting people from the pain of blood collection, the blood test chip technology provides 24-hour continuous blood monitoring. Real-time data can be transmitted to doctors' computers via Bluetooth and mobile networks. In this way, the doctor can maximize the tracking and control of the patient's physical condition. Currently, the technology is still in the experimental stage, and researchers hope that the technology will enter commercial applications within a few years.
The chip implanted in the human body not only has the above-mentioned monitoring function, but also can directly participate in the medical process. In 2013, American doctors implanted a child-assisted hearing chip for Grayson Clamp, which is only 3 years old. The chip helped the child recognize and process the sound, making him first aware of his father's voice. At present, more than a thousand people have accepted this operation and achieved varying degrees of success. However, most patients only have the ability to perceive the sound after surgery, that is, they can hear the beat, but they can't hear the melody.
At the same time, implanted chip technology has also brought hope to people with visual impairments. When the photoreceptor cells are severely damaged, blindness is caused, and the chip implanted in the eye can replace the damaged photoreceptor cells, directly stimulating the bipolar cells to generate signals, which are transmitted to the brain through the optic nerve. In other words, like a camera, a new sensor is replaced, and the other parts are original.
Risk and prospects
Although many of the above medical applications are endless and have broad prospects, human implanted chip technology has been controversial since its inception. The controversy over this technology focuses on both medical safety risks and privacy exposure risks.
From the perspective of medical safety, implanting a foreign object such as a chip into the body will definitely increase the risk of infection or immune system rejection. In addition, the chip is easy to implant and difficult to remove. Most of the chips with monitoring function are implanted into the skin by injection, and the operation process is not complicated. However, the battery and battery life of the chip are limited. If the chip is damaged or offset in the human body, how can the chip be safely removed?
If the medical safety risk is easy to hide, it can be solved through continuous advancement of technology, so the risk of privacy leakage is hard to prevent. Just as the Internet can't completely avoid "hacker" intrusion, human chip seems to be unable to avoid privacy theft. The human body chip is likely to be hijacked and utilized in the process of transmitting information. If the personal information data stored on the chip is stolen by criminals, the consequences will be unimaginable. How to make up for the shortcomings in the privacy and security of human body chips is a problem that must be solved in the process of promoting human body chip technology.
The plot of implanting chips in the human body in science fiction movies has gradually become a reality. Overall, this technology is still in its infancy and development stage, and there is no widespread commercial application. In the medical field, this technology has broad prospects, but the technical bottlenecks and security risks can not be ignored. Only by solving these two problems, human implanted chip technology can not only look beautiful.
