The APAD Smart Sleep Monitor uses optical fiber as the core component of its sensor. APAD uses the light attenuation caused by the deformation of the optical fiber caused by vibration, converts the light attenuation value into an electrical signal to calculate the change, and monitors human physiological activities without touching the human body. The system's sleep analysis is based on physiological changes such as heart rate, breathing rate, and physical activity status. APAD provides four major data including the heart rate, breath rate, bed exit status and sleep analysis. The built-in system alarms will send out an alarm once abnormal heart rate, breath rate or bed exit overtime is detected.
