Wireless Distributed Wearable Health Monitoring System

In this paper, through distributed design method, we design a wireless wearable system that can meet the demand of real-time monitoring of health data. The existing wearable instruments are usually in the hospital used by professional doctors or professional technicians. With a large number of connections, these complex and expensive devices are not convenient for real-time detection. This product combines the technology of wireless sensor and wearable systems, including research about wireless sensor nodes, wireless sensor network, and the measurement of temperature, oxygen saturation and motion state signal. This design uses the CC2538 chip, based on basic interfaces of Contiki, to realize the sensor class encapsulation of MLX90615, MAX30102 and LPB100. In addition, the APP on terminal equipment realize the data interaction with the center node. This system is in line with the characteristics of portable and dexterous wearable devices, and at the same time, it realizes the open modularization program mode, which is conducive to the expansion development. The terminal APP has the function of visual display of node data to achieve data exchange, realtime data visualization, historical data visualization and other purposes. This wireless distributed wearable system has the advantages of miniaturization, wireless, low cost, flexibility and easy to carry. It achieves the purpose of health monitoring and data collection and is suitable for the current market.
