Summary:PROBLEM TO BE SOLVED: To provide health control equipment for detecting the pressure change to bedclothes while a sleeping person breathes by optical fibers bedded between the upside of the bedclothes and his or her body, and to quickly and easily measure sleep apnea. SOLUTION: This sensor measures the change of transmission signal light or reflective light generated by excess loss caused from side pressure applied to optical fibers. Furthermore, plastic optical fibers are used as the optical fibers getting bigger by the change of the transmission signal light or the reflective light generated by excess loss caused from this side pressure.
