Micro Monitor for Four Physiological Parameters from Fingertip

Real-time monitoring and timely warning of human physiological parameters is very important and necessary for mastering an individual's health status. This project aims to select fingers with abundant blood vessels as the detection site, gather information on blood and vascular changes through photoelectric and temperature sensors, and extract features to obtain important physiological parameter values such as pulse, heart rate, saturation of peripheral oxygen, and body temperature, achieving the goal of multi-parameter synchronous monitoring. The results showed that the micro monitoring system has good stability and data accuracy with many characteristics such as small size, light weight, low power consumption, and easy portability. It is not only suitable for personal health monitoring, but also suitable for assisting medical workers in diagnosis and decision-making in professional settings. At the same time, it also provides a new approach and technical support for the field of mobile healthcare.
