Huawei bracelet for blood oxygen saturation detection function, as a non-medical equipment, the current accuracy in the daily use of scenarios, compared with the accuracy of medical equipment can reach more than 90%.
In the case of hypoxia or plateau areas, the user's oxygen level can also be detected, allowing the user to know their own oxygen level, which protects the user's oxygen health. For people who need to test their blood oxygen saturation over a long period of time, it is recommended to buy a professional blood oxygen detector. The blood oxygen detectors attached to various bracelets and watches are just able to display a number, and the price is not cheap.
Huawei bracelet B6 uses a new 1.53-inch flexible curved screen resolution of 460 * 188 pixels, compared with the previous generation of visual area increased by 50%. The curved form makes the bracelet fit better to the wrist and puts less pressure on the wrist.
Smart bracelet
The blood oxygen sensor chip used in the smart bracelet is reflective, and there are two light-emitting diodes in the chip, which emit red light at a wavelength of 669nm and infrared light at 880nm to the wrist. The photodiode on the other side is used to receive the reflected light, and the difference in light intensity between the emitted and received light can be used to calculate the saturation of blood oxygen.
Secondly, the B6 is powered by Huawei's Kirin A1 chip, which utilizes the latest Bluetooth 5.2 protocol, allowing for a longer Bluetooth connection distance and more stable calls. In terms of health features, new health features such as blood oxygen, sleep apnea, and atrial fibrillation premature beat screening are added to keep an eye on the user's health anytime, anywhere.
