Along with the development of computer technologies and digitization of human body's information, the digital human entered into a new stage of modelling physical features from the stage of reconstructing anatomical structures. By summarizing domestic and abroad relevant documents, we in this paper present the general scheme of digital human and the location of physical human as well as its conception and applied value. We especially analyze the modeling process of physical human, core technologies and its research and applications in four main fields: electromagnetic radiation, ultrasound propagation, bioimpedance measurements and biomechanical analysis. We also analyze and summarize existing problems of present physical human model and point out the future development trends of physical human.
