Will wireless charging of mobile phones cause cancer?

According to reports from World Wide Web, the latest "iPhone" scheduled to be released by Apple in the United States in 2017 may use a wireless charging module. Some people say that radiation from ordinary mobile phones must be prevented, let alone wirelessly charged mobile phones! Some people are even more worried about whether the radiation produced by wireless charging can cause cancer? To this end, the reporter interviewed Zhou Hongzhi, associate professor at the School of Applied Mathematics and Physics at Beijing University of Technology.   1. What does wireless charging of mobile phones mean? The principle of wireless charging technology is actually very simple. Zhou Hongzhi said, "The basic principle of the so-called wireless charging technology is the same as that of a transformer. It is the principle of 'electricity generates magnetism and magnetism generates electricity' that we learned in middle school physics class. With Take a mobile phone as an example. There is a magnetic core in the charger of the mobile phone, and a coil is wound around it, which can convert electricity into an electromagnetic field. The electromagnetic field can spread in space. At the same time, the mobile phone also has a corresponding receiving coil. This receiving coil comes into contact with the charging After the electromagnetic field emitted by the device is processed by a certain circuit, the mobile phone can be charged." 2. Can the radiation produced by wireless charging of mobile phones cause cancer? Zhou Hongzhi said, "Wireless charging of mobile phones will produce a certain amount of radiation, but as long as the quality is guaranteed and used correctly, this radiation is almost harmless to the human body and will not cause cancer. On the one hand, during wireless charging, the magnetic field is It is closed and has very little radiation to the outside world; on the other hand, as long as it is a product that has passed the national 3C certification, it will undergo strict inspection, and the radiation it generates must also meet certain standards and will not cause harm to the human body." 3. Will the radiation generated by various electronic products overlap? With the development of science and technology, people are exposed to more and more electronic products: computers, mobile phones, tablets, etc. Some people worry that electronic products will all emit radiation? Will these radiations be superimposed together to produce the effect of "1+1=2" or even "1+1>2"? Zhou Hongzhi said, "Electronic products all radiate, but as long as they meet the national 3C certification standards, they will not cause harm to the human body. As for radiation superposition, very strict conditions need to be met. In daily life, '1+1=2' Or there is almost no case of '1+1>2'. The radiation generated by various electronic products will interfere with each other, but will not superimpose each other. In many cases, they will even cancel each other. For example, many people throw objects into the lake at the same time. Pebbles, each pebble will form water waves, but these water waves will not superimpose into huge waves, and the same reason why radiation does not superimpose." 4. Why is the technology for wireless charging of mobile phones not popular? The technology of wireless charging for mobile phones has always been expected by people, but it has not been popularized so far. Is it because the cost is too high or it is technically difficult to realize? Zhou Hongzhi said, "Technically speaking, wireless charging of mobile phones can be achieved, and the cost is not high. The reason why this technology is not popular is mainly due to issues with standards and requirements, such as which specifications the charger should use. , how to seal the magnetic field, etc., these standards have not been officially released yet." However, Zhou Hongzhi said that once the relevant standards are officially released, the technology of wireless charging of mobile phones will soon become popular.

Wireless charging technology talks about technical principles

With the development of science and technology, various electronic products have emerged: mobile phones, watches, psp, mp3, iPod... They provide wireless convenience for our lives and greatly enrich our spare time life. However, various This kind of charger gives us a headache! The charger models of various electronic products are different, making it difficult to achieve good compatibility. However, the development of wireless charging technology has provided us with the best solution for charging portable electronic products, allowing all electronic products to be charged at any time as long as there are wireless charging equipment, greatly reducing our burden. Wireless charging theory is not a new technology. There have been many laboratories conducting research on this technology for hundreds of years. Due to the low efficiency of wireless charging, extremely short distance, poor safety and other factors, the promotion of this technology has been hindered. At this stage, the emergence of certain new materials and technological advancement have overcome the above shortcomings to a certain extent. The popularity of small household appliances and handheld terminals has provided a broad space for the marketization of low-power wireless charging, making it more suitable for the requirements of modern life and improving the quality of life. The development of the new energy industry has further promoted the innovation of this technology.   1. Development of wireless charging technology   In the 1830s, Faraday discovered that changing magnetic fields could produce electric current; then Tesla, one of Edison's assistants, also proposed the idea of wireless power transmission; Professor Xu Shuyuan from the Department of Electronic Engineering of City University of Hong Kong successfully developed a "wireless battery charging platform" in the early years, which requires the product to be in contact with the charger. It mainly uses the principle of near-field electromagnetic coupling. In 2007, Marin Soljasik and others from the Massachusetts Institute of Technology in the United States made new progress in wireless power transmission. They used a power supply two meters away to light a 60-watt light bulb "remotely". . On September 1, 2010, the Wireless Power Consortium (WPC), the world's first standardization organization to promote wireless charging technology, announced in Beijing that the Qi wireless charging international standard would be the first to be introduced into China. The WPC standard defines the types of inductive coupling (coil structures) and communication protocols used by low-power wireless devices. Brett Lewis, vice chairman of the Wireless Charging Alliance, said that there are nearly 60 alliance members, including Energizer, LG Electronics, Nokia, etc. Beijing time on November 9th, according to foreign media reports, the British company haloipt recently successfully implemented wireless charging for electric vehicles in London using its latest inductive power transmission technology. At this point, wireless charging technology adopts a unified industrial standard. In the next few years, mobile phones, MP3 players, digital cameras, notebooks, etc. will all use the same wireless charger. It can be said that certain industry standards have initially been formed in this field. The wireless charger currently on the market was invented by a British company. It looks like a mouse pad and is equipped with a dense array of small coils, which can generate a magnetic field and transmit energy to electronic devices with receiving coils for charging. , this receiving device can be easily attached to electronic devices like chewing gum. But so far, wireless charging technology still cannot be implemented well on high-power devices.   2. Principles of wireless charging technology   Currently, there are three main methods of wireless charging: electromagnetic induction, radio waves, and electromagnetic resonance.   3. Industry status of wireless charging products   As we all know, many people think that we live in a world surrounded by cables, which is troublesome, unsightly and environmentally friendly. This is why the idea of wireless charging was born. Although so far, various research institutions at home and abroad seem to have achieved There has been some progress, but it has always stayed in the low-power, short-range charging mode, and most international wireless charging research is developing in the direction of high-power and long-distance. Perhaps greater progress will be made in 20 years. Success, but no one can predict the future development. Scientists and engineers have long known that transmitting electrical energy does not necessarily require wires to be in physical contact at all times, such as the coils in electric motors and transformers. They can transfer energy to each other through the phenomenon of electromagnetic induction. Scientists have also discovered that radio waves contain electromagnetic radiation, but the efficiency of transferring energy from one point to another through traditional electromagnetic radiation is very low, because electromagnetic waves will spread around in the air, causing most of the energy to be lost. And this approach is also very dangerous, especially when the amount of electromagnetic radiation exceeds the range that the human body can bear. Moreover, wireless charging systems that use electromagnetic waves to transmit energy also have two major problems: first, the transmitter is still emitting energy when there is no device to be charged on the charging device, which will cause a waste of energy if it is not used for a long time; second, When a metal foreign object is placed on the transmitter, the electromagnetic waves will heat it, which will inevitably damage the device, or even cause a fire. Secondly, some wireless charging products have been unable to be put on the market in batches after perfect performances. Why? Because any electronic component must undergo precise debugging and calibration by professionals before leaving the factory. Similarly, if wireless charging products want to achieve a good electromagnetic resonance effect to achieve power transmission, they must undergo precise adjustment. In such a situation Under such circumstances, mass production will become very difficult. Finally, the cost of wireless charging products developed now is many times more than the price of an ordinary charger. No matter how advanced the product is, it is just a charging device after all, so if you want to promote it, you must work hard to reduce costs.    4. Exploration of new directions in wireless charging   First, to improve efficiency in a wireless charging system, it is necessary to minimize the magnetic energy loss between the transmitting and receiving coils. To achieve this goal, high-frequency and high-current equipment can be added to the transmitting coil to boost the transmit signal. By establishing an intelligent frequency following system and cooperating with LC resonance, a high magnetic potential magnetic field can be emitted. Due to the existence of high magnetic potential , can achieve the purpose of minimizing magnetic leakage, and install a certain magnetic field automatic search device in the receiving part to make the system work as efficiently as possible. And a certain magnetic field shielding device can be installed to reduce the harm of electromagnetic waves to the human body, and a certain coil can be wrapped in the shielding device to recover the magnetic energy that is not accepted by the receiving device, thereby improving the efficiency of the equipment. To solve the second problem, it can be achieved in this way: install a magnet on the receiving end, and only start sending energy when the transmitting end senses the magnetic force. This method is simple and feasible, because no one will accidentally put a magnet on the transmitter. Let it burn down on the device. To solve the mass production problem, the design of the wireless charging system must first focus on the resonance part so that the device can self-adjust. Only in this way can the mass production problem be solved. And if you want to reduce costs, you must do it in the form of chips, so that it is possible to reduce costs as much as possible. Furthermore, in view of the industry reality that most of the current wireless charging research focuses on high power and long distance, my opinion is that the focus can be slightly shifted and the wireless charging technology should be made as refined as possible. Since it is still Wireless realizes high power and long distance transmission, so why not develop into low power and medium distance? In fact, if this goal can be achieved, its application in the future electronic market is still very promising. We can use this technology to transform existing batteries. In various fields where disposable batteries are currently used, secondary batteries plus wireless charging can be used to reduce the use of disposable batteries. Since the battery is equivalent to a ball of metal, we can place a receiving coil inside the battery. The alternating magnetic field generated by the transmitting coil will cause the metal in the battery to generate eddy currents, which is converted into heat. At the same time, a reverse magnetic field is generated to offset the generation of the transmitting coil. The strength of the magnetic field causes the voltage received by the receiving coil to drop. In order to reduce the eddy current in the battery, a material that blocks the magnetic field must be placed between the battery and the receiving coil. This material is often called a "magnetic shielding material." However, the current research on this material is mainly focused on the environment with a strong magnetic field of 50Hz. There is almost no research on the strong magnetic field around 100KHz used in wireless charging, so this may be a direction for future development. Overall, wireless charging can be used in many imaginable and unimaginable fields. What is currently achievable include: low power and low energy consumption electronic communication products and office products, such as mobile phones, PDAs, etc., as well as furniture products and low energy consumption home appliances. The application fields that are currently being expanded include transportation, such as electric vehicles, EMUs, etc. Future long-term target areas include: space stations, satellites, warships and aircraft carriers, etc. It can even collect ionospheric energy from clouds and wirelessly transmit it to places that need energy, and it can be used in a new generation of international military fields that are completely environmentally friendly and energy-saving. Furthermore, in the specific promotion of products, another problem that needs to be faced is the formulation of industry standards. At present, there are no other industry standards except WPC. Therefore, in order to achieve final universality, all research directions should finally achieve a certain degree of "grand unification" and have a relatively mature and complete set of standards and protocols, so that the entire industry can truly Only by realizing universality can it be more convenient for users. While bringing wireless convenience to customers, it can greatly reduce the number of wired chargers and reduce the heavy pressure of electronic waste on the environment. It is the real convenience of our lives. Cleanliness.   5. Conclusion   The development of wireless charging technology is bound to bring wireless convenience to our lives. Perhaps some time in the future, all kinds of mobile phones, tablets, razors, cameras, toys, etc. around us will say goodbye to various chargers, and our lives will no longer be interrupted by various wires. At that time, we only needed to place our electronic products on a tablet-sized board to charge them. We should believe that under the background of the rapid development of existing technology, wireless charging technology should still be able to make greater progress in the next few years, so stay tuned.
