802.15.4 - based Efficient Wireless Sensor System Design for Monitoring Blood Oxygen and Heart Rate in IoT Medical Applications

Oxygen levels and heart rate joint monitoring is based on specialized, and most of the times, expensive oximetry devices. According to literature, many studies highlight the necessity of connecting oximetry devises, under well-known wireless protocols, such as Bluetooth, Wifi, ZigBee and others, for more efficient real time monitoring of human bio signals. However, most of the studies indicate a gap regarding an energy efficient and cost - effective end to end system for wireless monitoring of oxygen and heart rates, in IoT medical applications. To this end, our work, focuses on the design of a wireless oximeter device that bases its operation on the integrated and power efficient MAX30100 circuitry, and a customized lightweight ZigBee – based protocol for wireless bio signals transfer.
