2020 latest temperature measuring smart bracelet

Technology has matured at present:
1, the true temperature measurement, do not do any temperature compensation (infrared temperature measuring gun has temperature compensation), temperature measuring bracelet need to wear 5-10 minutes to be stable, not the instantaneous temperature measurement (infrared temperature measuring gun are measuring the instantaneous temperature), and the same principle of mercury thermometer, lasting temperature balance method is used, to ensure the high accuracy of the measured temperature.2. The temperature measured is the real temperature, which can be measured as the electronic body temperature with a medical accuracy of 0.1.3. Is it of medical reference value?Can you accurately alarm human body fever?There are three main problems: ambient temperature + temperature difference between human heart and wrist; temperature difference between human body and age; temperature difference between human body and body has been solved through high-precision solutions.
