Inclusion criteria
Inclusion criteria: 1. Gender distribution: At least 30% of the participants are male, and at least 30% of the participants are female; 2. Age distribution: Participants must be over 12 years old; 3. Wrist circumference distribution: (12.5 cm-21.5 cm) a) At least 20% of the subjects' wrist circumference should be within each quarter range of the total wrist circumference range; b) At least 10% of the subjects' wrist circumference should be within the upper eighth range of the total wrist circumference; c) At least 10% of the subjects' wrist circumference should be within the lower eighth range of the total wrist circumference; 4. Blood pressure distribution: a) At least 5% of the subjects should have a systolic blood pressure of = 160 mmHg (21.33 kPa); c) At least 20% of the subjects should have a systolic blood pressure of >= 140 mmHg (18.66 kPa); d) At least 5% of the subjects should have a diastolic blood pressure of = 100 mmHg (13.33 kPa); f) At least 20% of the subjects should have a diastolic blood pressure of >= 85 mmHg (11.33 kPa); The other blood pressure distributions are between these limit values (here, the blood pressure values are calculated based on the values read from the mercury sphygmomanometer); 5. Participants must be willing and able to follow the research steps and sign an informed consent form after understanding the research content; 6. Good compliance, able to cooperate in completing the entire clinical trial.
