Title:
ORGANIC ACTIVITY MONITORING METHOD, OPTICAL FIBER TYPE FLAT BODY SENSOR AND GARMENT TYPE OPTICAL FIBER TYPE FLAT BODY SENSOR USED IN THIS AND HUMAN BODY ATTACHING TYPE OPTICAL FIBER TYPE FLAT BODY SENSOR
Document Type and Number:
WIPO Patent Application WO/2007/026858
Kind Code:
A1
Abstract:
A large human activity such as waking up and a weak activity such as breathing and pulsing can be detected by a single device with high accuracy, whereby an organic activity monitoring system can be reduced in costs and improved in detection accuracy. Specifically, a method of monitoring the presence/absence of a human action and an organic activity in a living environment involving sleeping using a bed, bedding, a pad, and a tatami mat, wherein an optical fiber type flat-body sensor comprising an optical fiber fixed to or mixed in a flat body such as sheets of fabric is laid or place over, a light is introduced into the optical fiber from a light source, a change in the polarization condition of light propagating through the optical fiber, produced by a change in the shape of the optical fiber type flat-body sensor that is caused by a human action or organic activity, is detected by a polarization variation measuring device, and human activity or movement is judged by the detected value of the polarization variation.
