Wireless Wearable Devices and Recent Applications in Health Monitoring and Clinical Diagnosis

Human body contains much health information, which can reflect the basic health status and help detect diseases. However, the traditional wired transmission method greatly limits the portability and immediacy of the device. Turning the device into wireless can effectively solve the above problems. The development and research of new wireless wearable devices is urgent. This review focuses on wireless wearable devices applied in health monitoring and clinical diagnosis. Firstly, we introduce its development status and give emergent device system architecture. Then, wireless energy transmission and wireless data transmission modules are presented. Besides, this review categorizes the health information contained in the human body into three categories based on its signal states, and introduces measurement methods and existing applications. Finally, the outlook on the current challenges of wireless wearable devices is given.
