No strong radiation, no effect on the human body! The main principle is: the way of wireless charging is electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Most of the wireless charging of mobile phones uses the principle of electromagnetic induction.
Conclusion: Wireless chargers do produce electromagnetic radiation, although the value is usually 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.
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 thatThe healthy development of wireless charging technology.
Does wireless charging technology radiate the human body? Does it cause cancer? Tests have proved that wireless chargers can indeed produce electromagnetic radiation, but the value is relatively small. Now users are exposed to more and more radiation: computers, tablets, mobile phones, WiFi, televisions, microwave ovens... The cumulative radiation value is very high, and if the user lives in such a high radiation environment for a long time, it may cause serious harm to the body and mind.
The harm is relatively small can be ignored, although wireless charging technology has appeared in the 19th century, but the popularity of mobile phone applications is notLine chargers are not marked with radiation values, and electromagnetic radiation standards for wireless chargers have not yet been introduced. According to the Regulations on Electromagnetic Radiation Protection, the average specific absorption rate (SAR) of the whole body of ordinary users should be less than 0.02W/kg for any consecutive 6 minutes within 1 day and 24 hours. Wireless charging, the principle is inductive charging. Samsung uses the same technology in its flagship Galaxy phones.
3, the reporter carried out a test, the results show that the wireless charger does exist radiation, the value is small but not without. Tests show that the radiation value of wireless chargers is less than that of mobile phones, such as summerPu SH8010C and Samsung i579, but when used with other electronic devices such as computers, WiFi, the cumulative effect can not be ignored. In extreme cases, values above 2,500 can have a significant impact on health.
4, under normal circumstances will not harm the mobile phone, wireless charging now the working frequency is done below 1M, so the signal of the mobile phone will not have an impact. Wireless charging has no effect on mobile phone battery life, and wired charging is basically the same, but the rate is lower, but the wireless charger conversion rate is still high, more energy saving.
5, the test found that using a high-sensitivity radiation tester, the radiation value of the wireless charger is between 150 and 180, although compared to the 250 to 627 in front of the computer screen or the thousands of values when making a phone call, but the cumulative effect may not be ignored. At the same time, when wireless chargers, mobile phones, computers and other electronic devices are used together, the radiation value will increase significantly.
6, at the same time, the staff also measured the magnetic field radiation generated during the use of the mobile phone. Compared with wireless chargers, the radiation of mobile phones is much larger, and some mobile phones have a radiation value of up to two at the moment when the phone is connectedThousands, less some mobile phones, at the moment of connection, the value is also 427, and gradually dropped to about 200 after connection.
Reporters conducted a test, the results show that wireless chargers do exist radiation, although the value is small but not without. Tests show that the radiation value of wireless chargers is less than that of mobile phones, such as Sharp SH8010C and Samsung i579, but when used with other electronic devices such as computers, WiFi, the cumulative effect cannot be ignored. Values over 2500In extreme cases, it may have a large impact on health.
First answer no: Yes. The working power of the wireless charger is larger than that of the mobile phone, and the electromagnetic field energy radiated by the wireless charger is larger than that of the mobile phone.
Conclusion: Although the radiation of wireless chargers is small, the cumulative effect may have an impact on health, therefore, users should be vigilant while enjoying the convenience of wireless, and try to control the superimposed use of radiation sources to protect their health.
