Title: SWALLOWING MOVEMENT MONITORING SENSOR
Abstract:
This swallowing movement monitoring sensor (1) which determines swallowing movements of a subject includes: a contour change sensor (5) that is mounted on a subject's laryngeal part; and a microphone (20) that is mounted inside the subject's ear. The contour change sensor (5) includes an optical fiber sheet. The optical fiber sheet detects changes in the amount of transmission light based on loss caused by lateral pressure that is applied to the optical fiber from the laryngeal part relating to the contour change of the laryngeal part accompanying a swallowing movement. The microphone (20) detects swallowing sounds generated inside the ear relating to the swallowing movement.
