    摘要: A Baby Monitoring Mat is provided having a top mesh layer, a bottom mesh layer, two flexible sheets, and an optical cable. The optical cable can be routed between the top mesh layer and the bottom mesh layer. The flexible sheets are also between the top mesh layer and the bottom mesh layer forming a sensing area. A light source is provided for feeding light from one side of the optical cable to a photodiode for detecting light attenuation at the other end of the optical cable. A processor receives signals from the light source and photodiode and the signals are processed to determine movements and breath counts. The signals are generated based on the light attenuation changes along the optical fiber cable detected by photodiode. A method for monitoring baby on a mat is also provided.
