This paper explains a movment of 2024-2025. Agenda is as follows. Cooperation with Ethics Committee, Cooperation with Commitee on Social Engagement, and Member. In the course of our activities, I realized once again that we can get hints for future activities. We will continue to be aggressive in the future.

The main purpose of HEE is to consider the future direction of electrical engineering by studying the past. The history of electrical engineering forms the basis of the technology we need to develop. It is the starting point from which we should approach the future. This article presents the committee’s recent activities.

This report briefly presents activities of Technical Committee on Electromagnetic Theory (EMT), IEEJ. Our committee is now implementing the activities on 2025, which includes three times of the technical committee meeting and four times of technical committee conference. The report also contains three research topics presented in the technical committee meeting on EMT.

This review outlines the recent activities and long-term development of the IEEJ Technical Committee on Electromagnetic Compatibility. Emphasis is placed on the relevance of this field to SDGs, particularly in ensuring safe and resilient use of electronic systems and promoting electromagnetic environmental protection. The committee’s multidisciplinary efforts in evaluating biological effects, mitigating electrostatic discharges, addressing IoT device interference, and supporting regulatory standards are also introduced. These activities would contribute sustainable innovation and societal trust in electromagnetic technologies.

The Electric-Discharge, Plasma, and Pulsed-Power Technical Committee advances research from fundamental discharge phenomena to applied plasma processing and pulsed power technology. In 2025, it organized domestic workshops and supported international conferences. The committee also launched expert surveys on advanced diagnostics and SF₆ alternatives to promote sustainable and interdisciplinary technological development.

Topics in the field of “light application and visual science (LAV)” and activities of the technical committee of LAV field are generally reported. In addition, as a notable topic presented at a technical meeting of LAV recently, research results on peak wavelength measurements of fiber Bragg gratings with different reflectivities at the same wavelength are described.

The IEEJ Technical Committee on Instrumentation and Measurement has examined essential technologies within this domain through a series of technical meetings. Its recent initiatives and select prominent research findings are hereby presented.

This paper reviews the latest trend and front line of research activities in the field of dielectrics and electrical insulating materials (DEI) according to the papers presented in the 56th Symposium on Electrical and Electronic Insulating Materials and Applications in Systems held by the Technical Committee of Dielectrics and Electrical Insulation (TC-DEI), IEEJ, on Sept. 8 - 11, 2025, at The Himeji Chamber of Commerce and Industry, Himeji-city, Hyogo, Japan, as an in-person meeting. The recent activities related to TC-DEI are also introduced briefly.

Recently, the social implementation of superconducting technology has been active. This report covers the latest trends in superconducting technology applications, including topics related to fusion reactor applications, liquid hydrogen utilization, power applications, and energy-saving device applications.

This research committee was established in October 2024 with the aim of investigating cutting-edge technologies in traditional magnetic bio- and medical applications, while also taking into account the impact of and response to the COVID-19 pandemic, and to promote research into new biological magnetic phenomena and applications, as well as technological development trends that will lead to the next generation.

In this paper, bobbin coils are used as magnetic energy harvesting coils. Bobbin coils are low cost and have a high degree of freedom of shape. An equation is proposed to estimate the harvesting power of a magnetic energy harvesting coil from the mass and bobbin size of the bobbin coil. Electromagnetic induction experiments with the bobbin coil were carried out and the relative error to the harvesting power obtained confirms the agreement with the trend of the estimation equation.
