Sound monitoring based wireless healthcare and a typical implmenation for heart rate monitoring

This paper proposes a wireless healthcare system architecture that uses a wearable smart sensor to record the body sounds for health monitoring and diagnosis, which can prevent the damage to human bodies by those diagnosis instruments with active energy transmission such as X-ray detection and ultrasonic monitoring. A typical implementation of heart sound monitoring sensor is presented. The designed sensor records the heart beat sounds that can be used for real-time and long-term heart rate monitoring.
