<p><P>PROBLEM TO BE SOLVED: To provide a respiration sensor capable of reducing errors, miniaturizing a device and surely detecting even weak breath not only from the mouth but also from the nose or snores, a using method of the respiration sensor, and a respiration state monitoring device. <P>SOLUTION: A sensor body 3 is composed of a T-shaped moth respiration detection part 9 for detecting the breath from the mouth and a nose respiration detection part 11 bent perpendicularly to the mouth respiration detection part 9 so as to detect the breath of the nose. The mouth respiration detection part 9 is provided with a long-length distal end part 12 extended on a end side. The nose respiration detection part 11 is composed of a pair of left and right tabs 13 and 15. The sensor body 3 is composed of a roughly T-shaped and film-like piezoelectric element 16, and electrodes 19 and 21 composed of Ag foil are stuck to both upper and lower surfaces of a roughly T-shaped PVDF film 17 to obtain the piezoelectric element 16. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
