Most of the fitness tracker uses the oscillometric in morning and evening. This system measures the blood pressure automatically using an electronic sensor. The cuff of the smartwatch is inflated automatically as a result arteries become narrow and blood doesn’t flow through them. The pressure is then released slowly to allow blood to pass. As the pressure sensor detects arterial pulsations as oscillations. And when it reaches the maximum value is noted down which is used to calculate systolic and diastolic pressure. This is how blood pressure is calculated using the oscillometric technique.

The other technique that is used to measure blood pressure accuracy is PPG. It is a heart rate sensor that uses a pulse oximeter. This works on the principle of light absorption when the sensor illuminates the skin. However, they don’t have any inflatable cuffs technology that makes them less accurate than the sphygmomanometer. However, if user guidelines are followed properly then you can get the best results from it.
