Based on the research papers indexed by WOS core collections and by means of Cite Space,this paper makes a visualized exploration of the researchers, core documents and hot topics in the field of quantified self study. The results show that the researchers are concentrated in developed countries like the United States,and they focus mainly on hot topics such as the concepts and techniques of quantified self, its applications in the health service, and data management. Besides, there is hardly any cooperation between researchers, and the overall research output is rather limited.
