Abstract (in Japanese) (See Japanese page) 
(in English) We have been studying equipment to acquire cardiorespiratory information at home easily by piezoelectric sensors arranging on a seat surface of a chair. In our previous study, we suggested that heartbeat and respiratory components could be extracted using independent component analysis to signals obtained from piezoelectric sensors. However, there was a problem that analysis became difficult due to the influence of body movement noise by the user. Therefore, in this study, we studied the method of body movement noise removal or reduction. Moreover, heartbeat intervals, which were obtained from removed body movement noise, were compared with those which have been achieved from the electrocardiogram. As a result, we could obtain 3.1±0.5% error rate. Additionally, we obtain 4.2±0.7% from the original waveform, so the proposed method reduced it by 1.1%.
