Background and Purpose
The Institute of Electrostatics Japan (IESJ) is working to expand its international research network to enhance global visibility and promote academic collaboration. As a first step, IESJ local branches plan to hold a joint research exchange meeting with researchers from Taiwan and Japan, aiming to initiate academic interaction in the field of electrostatics. To support this initiative, we invited Prof. Lin of National Sun Yat-sen University (NSYU) to serve as the organizer, and he kindly agreed to our proposal. Through open discussion, we hope to deepen our understanding of electrostatic phenomena and foster the development of new international research partnerships.

Prof. Seiji Kanazawa (Oita Univ.)
“Electrostatics — An Old Yet Ever-Evolving Field”
Electrostatics is often described as an old yet ever-evolving field of study. It is closely linked to electrical discharge phenomena, which in turn lead to plasma generation. This lecture will present an overview of modern electrostatic applications, framed by a historical perspective on electrical discharge and its development. It will also highlight key future challenges in the field. Furthermore, the current state of electrostatics research in Japan’s Kyushu region will be introduced, with particular emphasis on the relationship between electrostatic phenomena and semiconductor technology.

Prof. Koichi Takaki (Iwate Univ.)
“Production of high-current glow plasma for high-speed material process”
Pulsed power technology was employed to generate a glow discharge with a large current exceeding 100 A. The gas pressure was varied from atmospheric pressure down to 10 Torr. The glow‐sustaining time was estimated using input energy density in cathode fall region. The electron density of grow plasma increased from 1010 to 1011 cm⁻³ at transient of glow mode from normal to abnormal. Global model analysis indicated a significant shift in the balance of ion and excited-state species near the transition from the normal to abnormal. The carbon film was prepared using the pulse glow.

17:00-17:15 Research Presentation (5)
Mr. Toshio Uehara (TTY. Ltd., Visiting researcher of Nihon University College of Science & Technology, Former CEO of Trek, Inc. and President Trek Japan K.K.)
“Introduction of High Voltage Electrostatic Force Microscopy (HV-EFM)” The precise characterization of surface voltage distributions on charged surfaces with high spatial resolution is critical for a wide range of scientific and technological applications. Conventional electrostatic voltmeters typically provide spatial resolutions no finer than approximately 1 mm in diameter, which constrains their ability to resolve localized charge variations. To overcome this limitation, we have developed a high-voltage electrostatic force microscopy (EFM) system that achieves spatial resolutions on the order of 10 µm in diameter. The instrument accommodates measurement voltages from 0 to ±2 kV and supports scanning areas extending over several square centimeters. This apparatus enables the detailed and accurate mapping of surface potential distributions with substantially improved resolution relative to existing measurement techniques.

“Electrical Behaviors & Standardization of Submicron Bubbles for a Sustainable Humanosphere” (Prof. Ueda)
https://www.rish.kyoto-u.ac.jp/center_future/unit/unit3/
We present how international standardization and research design for fine and ultrafine bubbles intersect to advance a sustainable humanosphere. Impedance spectroscopy and compact equivalent-circuit models resolve Maxwell-Wagner-Sillars polarization, linking interfacial charge and zeta potential to radical generation and pollutant removal. We propose ISO-aligned, practical metrics for electrical characterization to guide scalable, energy-efficient applications.
