3, the second is wireless charging. This is not available. Probably because as much room as possible was left for the battery, so it was castration. The next step is that camera recognition is not at the 3D level. This ordinary camera level, also cheated children, money. Grade can only be identified by fingerprints on the side. Slim and slender, no on-screen fingerprint recognition. I don't know if it's the space.
4, in addition, electrical appliances related to mobile phone accessories are also very practical. The wireless charger solves the problem of charging cable entangling and charging port damage, and the mobile power supply ensures that I am outdoors or travelingHarm. For this view, He Guili, director of the Tel Laboratory of the Telecommunication Research Institute of the Ministry of Industry and Information Technology, agreed: "Wireless chargers as long as they are done in accordance with technical specifications, there will be no radiation harm to the human body." But there is a key problem.
Radio wave type space charging technology is passed to the mobile phone in the form of "millimeter wave" extremely narrow beam, there is no experimental data to show that millimeter wave will bring radiation, that is, millimeter wave radiation will not bring negative effects on human health.
Conclusion To reiterate: the radiation of wireless chargers is small, but the cumulative effect may have an impact on health, therefore, withWhile enjoying the convenience of wireless, households need to be vigilant and try to control the superposition of radiation sources to protect their own health.
The body has a strong response to electric fields, but the body has almost no response to magnetic fields, so this system does not affect human health. As an electronic charging product, the charger itself avoids the radiation, so it is inevitable that the wireless charger has radiation. However, the current power of the wireless charger is very small, the charging time is longer, the radiation generated is also small, and it should not cause great harm to people.
YesIn the electromagnetic radiation safety issues that consumers are worried about, the standards introduced this time stipulate that wireless charging the electric vehicle charging, electric vehicles inside and outside the electromagnetic environment limits and test methods, specifically listed in a variety of frequency ranges and the corresponding electric field strength and magnetic induction intensity indicators. However, the situation of superposition after installing 10 or 100 units has not been tested in large quantities.
There is a little radiation, as long as the person is not between the transmitter and the receiver, the radiation level is very small, and the charging frequency is inconsistent with the main absorption frequency of the human body, the harm is completely negligible.
For the human body: wireless charging technology is safe and harmless to the human body. The resonance principle used by wireless charging is magnetic field resonance, which is transmitted only between coils resonating at the same frequency, and other devices cannot accept the band, in addition, the magnetic field used by wireless charging technology is itself harmless to the human body.
In fact, it is certain to tell you that the harm of wireless charging to the human body is very small, almostIt's negligible. This is like the Wi-Fi, mobile phones, TVS and other electronic products we usually use, and we do not exist between the transmitter and the receiver the radiation level is small, and the main frequency absorbed by the human body is inconsistent with the charging frequency, so we can not worry about the harm of wireless charging. In theory, wireless charging technology is safe and harmless to the human body, the resonance principle used by wireless charging is magnetic field resonance, which is only transmitted between coils resonating at the same frequency, and other devices cannot accept the band, in addition, the magnetic field used by wireless charging technology is itself harmless to the human bodyYes.
With the development of the mobile Internet, the rise of wireless charging has led to discussions about electromagnetic radiation. Although the wireless charging technology used in smartphones by Nokia and other brands is convenient, the electromagnetic radiation caused by the use of the technology has raised concerns. The health effects of electromagnetic radiation are complex and require long-term studies to determine its long-term effects, just as secondhand smoke is known to cause cancer.
