<P>PROBLEM TO BE SOLVED: To provide a living body monitoring device which can detect only slight motion such as heart beat vibration and securely detect vibration even when a laying position of a subject is shifted. <P>SOLUTION: The living body monitoring device includes a resonance plate 10 for laying a subject, a polymer piezoelectric film sensor 20 adhered on the lower surface of the resonance plate 10, and a lower case 30 forming a space between the case 30 itself and the resonance plate 10 to detect at least one vibration of the heartbeat or the breath of the subject. The lower case 30 is configured into a dome shape wherein the center leaves from the resonance plate 10 further than four corners. <P>COPYRIGHT: (C)2012,JPO&INPIT |
