Internet of medical things: A systematic review

Internet of Medical Things (IoMT) refers to applying Internet of Things (IoT) into the medical field. The IoMT enables a medical system to connect various smart devices, such as wearable sensors, medical examination instruments, and hospital assets, for establishing an information platform. These smart devices act as the basic nodes in an IoMT system, collecting or generating health data and transmitting the data to the server for further processing and analysis. Physicians apply health data to make better medical decisions. Recently, the IoMT has been widely applied in many areas, including smart hospital, remote health monitoring, disease diagnosis, and infectious disease tracking. In this review, we investigated the IoMT from its concept and theory to its deployment domains, adopted technologies, and applications. We provided theoretical explanations with various examples and more than one hundred representative references. We also presented a cutting-edge discussion for the challenges and directions of the IoMT. We hoped that this systematic review would be beneficial to readers of all levels and backgrounds, including industry beginners, medical institution administrators, policy makers, and experienced researchers.
