At the same time, it can be used in real time through the smart watch.

[0004] Existing smart watches use the built-in heart rate and pulse detection modules on the dial to detect the wearer's heart rate and pulse data from the back of the hand, but cannot detect the radial artery at the wrist, making it difficult to effectively improve the detection accuracy. On the other hand, existing smart watches lack wearing auxiliary facilities, resulting in them having to be worn with one hand, making the wearing process cumbersome and inconvenient to operate.
