Health Internet of Things: Recent Applications and Outlook

The Health Internet of Things (Health-IoT) is a milestone of the health information system development, and it will play an important role in improving people's healthy level and enhancing the quality of life and health service level, and will promote the change of health service mode. Health-IoT is a very complex system, involving computer science, microelectronics systems, wireless communications, medical and health, and many other related fields. In this paper, we review the background and state-of-the-art of Health-IoT. We first introduce the general background of Health-IoT and the difference between Health-IoT and traditional IoT are given. Then we give the definition of Health-IoT and the Health-IoT's features. We then focus on the researches closely related to the Health-IoT, including physiological information collection, data transmission, wearable computing, and health big data analysis. We introduce the four typical application scenarios of the Health-IoT, including the medical industry, health monitoring, exercise promotion and mental support. Finally, we give the outlook of Health-IoT and the summary.
