According to the development status of wearable technology and the demand of intelligent health monitoring, we studied the multi-function integrated smart watches solution and its key technology. First of all, the sensor technology with high integration density, Bluetooth low energy (BLE) and mobile communication technology were integrated and used in develop practice. Secondly, for the hardware design of the system in this paper, we chose the scheme with high integration density and cost-effective computer modules and chips. Thirdly, we used real-time operating system FreeRTOS to develop the friendly graphical interface interacting with touch screen. At last, the high-performance application software which connected with BLE hardware wirelessly and synchronized data was developed based on android system. The function of this system included real-time calendar clock, telephone message, address book management, step-counting, heart rate and sleep quality monitoring and so on. Experiments showed that the collecting data accuracy of various sensors, system data transmission capacity, the overall power consumption satisfy the production standard. Moreover, the system run stably with low power consumption, which could realize intelligent health monitoring effectively.
Recently, with the development of technology, the 5th generation mobile communication technology (5G) is developing day by day. Mobile medical industry has a huge market in our country. As a strategic emerging industry in China, 5G will focus on the medical care industry, enhance the service quality of medical care, enable innovative applications and services, and make the medical industry more digital, networked and intelligent. 5G has an epoch-making significance for improving the quality of health monitoring and self-care ability, and promoting medical care development. Therefore, this paper introduces the definition, advantages, and significance of 5G and its application status in medical care, in order to lay a foundation for promoting the deep integration of 5G and medical care.
