<P>PROBLEM TO BE SOLVED: To provide a living body sensing vibration sensor device which senses and notifies the presence/absence of vibrations, the intensity of the vibrations, the discrimination between a human being and an article based on the duration of the vibrations, the presence/absence of the human being, and a health abnormality from the state between a stationary and a moving states in such a manner that the vibration by the heart beat of the heart, the vibration by the pulmonary respiration, and detects the vibration by the movement of the body when the human being comes into contact with a film-form high sensitivity vibration sensor which can detect minute vibrations without restraint. <P>SOLUTION: This living body sensing apparatus has a living body vibration sensor means of a porous polypropylene electret film which detects the vibration by the heart beat of the heart of the living body, the vibration by the pulmonary respiration, and the vibration by the movement of the body, and outputs an oscillatory voltage signal. <P>COPYRIGHT: (C)2008,JPO&INPIT |
