Pulse wave transit time (PWTT) is used as a non-invasive and cuffless method for blood pressure estimation. In this paper, we design a system that can measure PWTT by monitoring ECG and pulse wave continuously. The system includes analog signal sampling in PCB, signal display and data processing in computer. We measure pulse wave by the photo-plethysmograph (PPG) device in finger which includes an infrared LED transmitting light, photodiode in OPT101 as detector, amplifier and filters. We… CONTINUE READING
