One of the most popular measurement needs is the sphygmomanometer for cardiovascular health. With the development of modern medical technology, sphygmomanometer has become automatic, low cost, and light. However, most of them cannot improve knowing the correct blood pressure value continuously. A few can achieve a continuous time measurement of the sphygmomanometer is expensive, only the hospital is available. The inertial sensor is small, low power consumption, low cost, easy development and integration, high sensitivity. Because that, there are more and more products like smart wrist watch, smart phone, etc., and the study also appeared of the heart signal measurement, such as Seimocardiography, or continuous time blood pressure monitor. In this study, two gyroscope chips and a self-developed microprocessor system board were used to collect blood flow time beat to beat. The systolic blood pressure of the subject was then examined using the concept of the relative value of the systolic blood pressure using the blood flow time to confirm if the value is correct. We will compare the results of using the flow time to measure the relative value to calculate systolic pressure of the algorithm and the instrument on the market, then record the results. To be compared with previous studies will confirm whether this method is more progressive.
