This study proposes the structure of sensitivity amplification sensor that contains piezoelectric film for heartbeat and respiratory monitoring. Both ends of a flexible arch-type plastic sheet are fixed on both ends of piezoelectric film, which is shorter than the arc length of the arch-type plastic sheet. While a subject (an adult) is in supine resting and his thorax compresses the sensor, the arch-type plastic sheet deforms and generates tension over the piezoelectric film. The experiment proved that the output signal of the arch-type sensor increased about twice as much as that of the sensor simply contains piezoelectric film. In addition, this study focused on the successful separation of heartbeat signal from respiratory signal.
