Bibliometric Analysis on the Literature of Body Temperature Measurement Technologies over the Past Two Decades

This study aims to explore the research hotspots, and trends in the field of body temperature measurement technologies and provide a theoretical basis for the research development and application of body temperature measurement technologies. Literature on body temperature measurement techniques in the Web of Science core database was searched and used for bibliometric analysis. A total of 1,042 papers were included. In recent years, the number of articles published in this research area has been increasing year by year. In addition, the largest keyword clustering in this research area is magnetic resonance thermometry. High-frequency and emergent keywords in recent years include infrared thermography, magnetic resonance thermography, wearable sensor, etc. The field of temperature measurement technology research is currently in a phase of rapid development. The current key focus of research in this field is how to improve the accuracy of temperature measurement, simplify measurement conditions, and expand the range of measurement scenarios.
