Space charging technology is actually an electromagnetic radiation wireless charging QI radiation standard charging wireless charging QI radiation standard With the development of mobile phone technology, wireless charging has become popular, there are rumors that wireless charging this "air charging" technology produces strong radiation, which will harm health. Truth: Wireless charging technology according to the technical principle, can be divided into three categories, namely electromagnetic induction, magnetic resonance and radio wave.
Radiation will certainly be present, but not the current vacuum chargeElectricity, there is no evidence of harm to the body radiation standards and space area relationship. According to the safety limit set by the International Non-Ionizing Radiation Research Committee, the safe range of radiation that the human body can withstand is 10 watts/square meter. According to the calculation of 90 square meters of family housing, residents can withstand the maximum radiation power of about 900 watts.
Thus does not cause any DNA changes to the object. And there is no experimental data to show that millimeter wave radiation will have a negative effect on human health. Today, millet launched the space charging technology, this technology debut is more conceptual. Air separation charging technologyThe commercial use of smart phones still needs to solve a series of problems, including safety, regulations, costs, and so on, and it will take several years to be conservative.
Space charging should refer to the current wifi charging, as well as power line charging, and wireless charging and other technologies. Now there are relevant international technical standards to specify this wireless charging technology.
Radiation, in fact, every electronic product has, but it can indeed be omitted, after all, the amount of radiation is too small. Therefore, the problems existing in Xiaomi's air separation charging technology will also be slowly visible in the future, for exampleFrom the current point of view, it can only achieve within 5m.
Conclusion: Wireless chargers do produce electromagnetic radiation, although the value is passableUsually small, but should be wary of its possible cumulative effect. With the popularity of wireless charging technology, users are exposed to more and more radiation sources in daily life, such as mobile phones, computers, WiFi, etc., and long-term accumulation may have an impact on health. Wireless Charging Technology and controversy With the development of mobile Internet, the rise of wireless charging function has led to a discussion on electromagnetic radiation. The staff of the Communications Department of the Ministry of Industry and Information Technology said that it is inevitable that the wireless charger has radiation, but since it has been listed, it means that it must meet international standards and will not cause great harm to the human body. And for this view, the Ministry of electricityThe rise of line charging has led to discussions about electromagnetic radiation.
In summary, the radiation problem of wireless chargers does exist, but the extent of its impact on human health is uncertain. In the use of wireless chargers, safety guidelines should be followed, and researchers are expected to provide more scientific evidence about their radiation effects to ensure the healthy development of wireless charging technology.
Many wireless chargers on the market do not indicate the radiation value, and the electromagnetic radiation standard for wireless chargers has not yet been introduced. According to the "Electromagnetic radiation protection Regulations", ordinary users within 1 day and 24 hoursThe average systemic specific absorption rate (SAR) should be less than 0.02W/kg for any 6 consecutive minutes. Wireless charging, the principle is inductive charging. Samsung uses the same technology in its flagship Galaxy phones.
Conclusion: Wireless chargers do produce electromagnetic radiation, although the value is relatively small, but the cumulative effect can not be ignored, users need to be vigilant. With the popularity of wireless charging, the problem of radiation gradually surfaced. Wireless chargers transfer electrical charges through the air, and their working principle involves electromagnetic radiation. Experts say any wirelessly connected device generates electromagnetic waves, yesThe effects in humans are complex and require long-term study.
