ABSTRACT
Medical and health equipment are rapidly developing in the direction of intelligence and portability. As a representative of them, wearable devices are playing an more and more important role in medical service. To this end, this review discussed the development process of wearable devices, and defined the concept of wearable devices. The existing wearable devices were divided into four categories according to their shapes: hand wear, head wear, lower limb wear and trunk wear. The application of them in medical service were particularly introduced. The 4 future development trends of wearable device, included adding fashionable element, focusing on a particular area, new interactive model and invisible portability, were analyzed and reviewed. Based on above analysis, we could got a comprehensive understanding for the application of current wearable device in medical treatment, and could hold the development direction of wearable device in medical treatment of hospital. While, for above products, there were some differences in technique level between domestic manufacturer and developed country, and there is a larger potential in the relevant products and arithmetic aspects.
