RESPIRATION SENSOR, USING METHOD OF RESPIRATION SENSOR, AND RESPIRATION STATE MONITOR

摘要

A respiration sensor capable of detecting breath from mouth or nose and snoring while suppressing error and reducing the size of the device, and its using method and a respiration state monitor. The sensor body (3) of a respiration sensor (1) is a thin film-like member folded chevronwise at the central part (laterally line-symmetry axis of the sensor body (3)), and consists of a respiration detecting section (11) for detecting breath from mouth and nose, and a pair of legs (13, 15) projecting from the right and left ends on the rear end side of the respiration detecting section (11). The sensor body (3) consists of a substantially T-shaped film-like substrate (17), and a rectangular piezoelectric element (19) stuck to the inside of one inclining surface of the chevron. The respiration detecting section (11) has a rectangular shape folded to project upward and being arranged to oppose the breathing direction of mouth (arrow A direction) and in parallel with the breathing direction of nose (arrow B direction).
