中文摘要	We present a ballistocardiogram(BCG)measurement system for obtaining the BCG signal.The performance of the BCG measurement system was tested,including the dynamic response frequency of the platform(32 Hz with a 75 kg load),and the signal to noise ratio of the system(minimum 23 dB).Factors that could influence BCG recording during measurement were investigated by collecting data from 48 healthy subjects(28 males and 20females).The basic features of the BCG signal,such as the amplitude and time interval,were extracted,and differences by gender were analyzed.A correlation between the IJ amplitude(amplitude difference between I-and J-peak)and the respiration phase was found(R2=0.49).The BCG signals for both sitting(SiBCG)and standing(StBCG)postures were obtained using this system.These showed that the StBCG amplitudes were larger than those of SiBCG but there was no significant difference in the time intervals.The robustness of our system was verified,and its potential for non-invasive cardiac activity monitoring was demonstrated.; We present a ballistocardiogram(BCG) measurement system for obtaining the BCG signal.The performance of the BCG measurement system was tested,including the dynamic response frequency of the platform(32 Hz with a 75 kg load),and the signal to noise ratio of the system(minimum 23 dB).Factors that could influence BCG recording during measurement were investigated by collecting data from 48 healthy subjects(28 males and 20females).The basic features of the BCG signal,such as the amplitude and time interval,were extracted,and differences by gender were analyzed.A correlation between the IJ amplitude(amplitude difference between I- and J-peak)and the respiration phase was found(R2= 0.49).The BCG signals for both sitting(SiBCG) and standing(StBCG)postures were obtained using this system.These showed that the StBCG amplitudes were larger than those of SiBCG but there was no significant difference in the time intervals.The robustness of our system was verified,and its potential for non-invasive cardiac activity monitoring was demonstrated.
