Portable smart blood pressure monitor based on MediaTek MT6381 + Airoha AB1601

With the improvement of living standards and the increase of life pressure, the incidence of hypertension is getting higher and higher, and the resulting complications such as stroke, heart disease, hemangioma, kidney failure and other diseases have gradually become the main threat to human life. In fact, traditional mercury blood pressure monitors measure blood pressure most accurately, but because their operation requires a certain amount of expertise, it is difficult to popularize them in the home. Electronic blood pressure monitors that are convenient for measurement have also developed rapidly, but there are still many users who complain that the volume is too large, so is there a more convenient electronic blood pressure monitor? MediaTek introduces the AB1601+MT6381 portable solution. The biggest advantage of this solution is that it can measure 6 physiological data such as heart rate, heart rate variability, blood pressure trend, blood oxygen saturation (SpO2), electrocardiogram (ECG), and optical volume pulse wave wave (PPG) with only one chip, and can be integrated into smartphones, wearable devices and other terminals, and the measurement time is only about 60 seconds. The MT6381 hardware module highly integrates front-end signal processing, a variety of sensors, and other electrical and optical components. Through AB1601, the Raw Data is directly transmitted to the mobile APP through BLE, and the mobile APP realizes the processing of the Raw Data data and displays it directly in the mobile APPK.
