Research in the field of smart wearables from 2006 to 2019: a bibliometric analysis and visualization based on citespace

Abstract

Smart wearable devices have been developing rapidly in recent years. Based on the core database of Web of Science, a total of 4313 literatures from 2006 to 2019 were screened out to make a comprehensive review. Citespace was used for graph metrology analysis. The main findings are as follows: first, the most important developments occurred in China, the United States, and South Korea. China, in particular, has dominated the theory, with the most records and close cooperation with many countries or regions. Second, several universities and research institutions play important roles in collaborative networks, and the most influential central author is Zhonglin Wang. Thirdly, the research focus has changed from high concentration to diversification, and the existing research fields are extensive. Finally, through direct reference analysis, co-citation analysis and co-citation cluster evolution analysis, key literature, milestones in the history of theoretical development, research hotspots and trends are identified and visualized. Through sorting out the dynamic evolution process of knowledge cluster, this empirical study is of great significance to construct the prospect of intelligent wearable theory.
