Abstract :
In this paper, we propose a measuring device implementation to measure ECG, 50 KHz BIA for getting BIA/respiration, and 10~50 Hz GSR for measuring electrical characteristics of skin. To this end, BIA signal is separated by line filter and high impedance element and the interference between signals could be minimized by switching in time domain to separate ECG and GSR signals having the similar frequency range. ECG, heart rate and respiration are measured by the simulator based on the implemented circuit and BIA and GSR impedance are verified using standard resistance. Also, we made an experiment this method to human body and found the possibility of detecting bio-signals
