Description
Ambient Sensor based respiratory rate monitoring has been one of the emerging and most attractive field of research in of healthcare advancements. Market study shows that there is multidisciplinary need for continuous monitoring of vital signs. A set of ambient vital sign monitoring sensors are studied in thesis. Pyroelectric infrared (PIR) sensor is used for non-contact based resting respiration rate estimation. This infrared system monitors and records the chest motion of a subject using the analog output signal of the PIR sensor. The analog output signal is a composite motion of the inhale-exhale process and the vibrations of heartbeat. This system proposes a low cost and an effective way to estimate the respiratory rate, which is an important biological marker. Respiration rate is estimated based on the inhale and exhale breathing chest motion detected by the pyroelectric infrared sensors. This thesis aims to review the literature on contact and non-contact methods of respiratory monitoring and to propose a non-contact system for respiratory rate monitoring and estimation
