Speaking of smart wear sphygmomanometer, compared to we have not unfamiliar, although not officially started selling, but many of its friends have been very much looking forward to. Appearance, functional aspects of the front is very much, today we are no longer careful to explain. We can search the relevant information online.

Because of the particularity of intelligent wear sphygmomanometer, only need to wear on the wrist, the thumb and index finger gently touch the fuselage on both sides of the metal, you can monitor blood pressure.

Monitoring principle: When we know heart rate, photoelectric volume pulse wave PPG, ECG ECG, you can calculate the blood pressure. Our blood pressure is not measured, but by the calculation come. This algorithm is called PWTT algorithm, that is, the use of ECG and pulse wave measurement of blood pressure.

Its principle is: the pulse wave transmission speed and blood pressure is directly related to high blood pressure, pulse wave transmission fast, otherwise slow. The pulse transmission time (PWTT) can be obtained by the ECG ECG and pulse wave signal PPG, together with some of the conventional body parameters (such as height, weight) can be obtained pulse wave transmission speed, and then calculate the blood pressure value.
