<P>PROBLEM TO BE SOLVED: To provide a means for simultaneously measuring both electrocardiographic signals and respiratory information with sufficient accuracy using three electrodes. <P>SOLUTION: A biological signal measurement device includes: first-third electrodes 11-13; ground 16 connected with each of the first-third electrodes 11-13 via capacitors 20-22 (or resistors); a first separation circuit 14 to which signals from the first electrode 11 and signals from the third electrode 13 are input respectively via buffers 17 and 19, and the ground 16 is connected as the ground of the circuit; and a second separation circuit 15 to which signals from the second electrode 12 and the signals from the third electrode 13 are input respectively via buffers 18 and 19, and the ground 16 is connected as the ground of the circuit. The first and second separation circuits 14 and 15 have a separation filter for separating the input signals into respiratory components and electrocardiogram components. <P>COPYRIGHT: (C)2013,JPO&INPIT |
