AC Impedance Calibration Research Landscape: A Bibliometric Study of Scopus Publications (2010-2024)

AC impedance calibration plays a vital role in ensuring measurement accuracy across electrical engineering applications, particularly in energy storage systems, biomedical instrumentation, and precision electronics. As technological demands grow, understanding the evolution of research in this field becomes essential for guiding innovation and standardization. This bibliometric study maps global trends in AC impedance calibration research from 2010 to 2024, based on 4,227 Scopus-indexed publications. The analysis reveals a 30% surge in publications (1,262 papers) between 2022 and 2024, largely driven by industrial demand in energy storage and precision instrumentation. China leads the field with 37% of total output, with key contributions from institutions such as Southeast University and authors like Yin Xiaokang. Keyword analysis highlights dominant themes including electrical impedance measurement (3,215 occurrences), electrochemical impedance spectroscopy (EIS), and emerging applications in lithium-ion batteries. While strong national collaborations are evident particularly in China international partnerships remain limited. The study emphasizes the need for standardized methodologies and the integration of AI-enhanced calibration techniques to address persistent measurement uncertainties.
