<P>PROBLEM TO BE SOLVED: To provide a biological information aquisition system allowing a subject to relatively freely change its position, which does not physically and mentally restrain the subject and collects its biological information without imposing any operational burden on the subject. <P>SOLUTION: The biological information aquisition system has a body vibration/air pressure conversion means to be fixed on a body part of the subject and to convert body vibration of the subject to a variation of an air pressure in an airtight space, and a sensor means to convert a variation of the converted air pressure to electric signals. The body vibration/air pressure conversion means comprises, for example, an air pad to be fixed on the body part into which air is inserted, and an air tube communicating with the air pad. <P>COPYRIGHT: (C)2009,JPO&INPIT |
