A New Design of PPG Pulse Sensor and Noise Analysis

A new photoplethymograph(PPG) pulse sensor for long tern,continuous monitoring is presented in this paper.The PPG pulse sensor is attached to the finger base for monitoring beattobeat pulsation.Comparing with the traditional design,the pulse sensor uses a new integrated chip,which is integrated the photosensitive unit and the signal amplifier.This design can efficiently remove the system noise and improve the precision of measure.In the experiment,using the new PPG pulse sensor can measure the pulse directly from the pulse in real time.At the same time,making the noise analysis and dealing with the measure noise,and getting a good pulse wave.
