一种基于绿光的可穿戴式光电容积脉搏波测量系统
A wearable photoplethysmography measurement system based on green light
摘要
Abstract
The pulse wave contains rich hemodynamic information. The non⁃invasive method used to detect the pulse wave and deduce the physiological and pathological features of human cardiovascular system becomes the research hotspot. A set of wearable pulse wave extraction device was designed,which includes MCU control module,signal acquisition module,power supply module,and Bluetooth module. The principle of photoplethysmography(PPG)to acquire the pulse wave is analyzed. The luminous diode at 523 nm and environmental optical sensor are taken as the core of the device. The hardware development mod⁃el is described in detail,and the key codes of signal processing are given. The experiment results indicate that the designed pulse wave extraction device can describe the pulse wave of wrists,fingers and forehead,and has good applicability.关键词
