碩士 === 國立交通大學 === 電機工程學系 === 103 === The generation of photoplethysmography(PPG) signal is based on the acroteric microcirculatory blood and the wavelength designed for the measurement of specific elements. The PPG signal can be used to analyze and calculate the physiological parameter because it is and the wavelength designed for the measurement of specific elements In this study, it proposes a multichannel PPG measurement hardware platform system with the analog multiplexer to reduce others analog elements. Further, using the measured data which is acquired from the system is used to perform series analyses, such as heart rate and blood pressure with PPG signal [1] acquired from individuals’ left cheek. Besides, this system can measure the motion PPG signal which is obtained from the index finger of the left hand with about 5 to 10 cm shaking to analyze the heart rate and blood pressure.
