COMMISSION K: ELECTROMAGNETICS IN BIOLOGY AND MEDICINE(November 2020 – May 2023)
Introduction
In the field of radio science, various researches have been conducted on the relationshipbetween radio waves and the human body. Portable wireless terminals have been widely used in thefield of wireless communication, and magnetic resonance imaging devices and thermal cancer
treatment devices have been put into practical use in the field of medical applications. In addition, in
recent years, devices and equipment that use electromagnetic fields, such as wireless power supplies,
sensor networks, and magnetic levitation trains, have become widely used. In addition, in the medical
field, surgical devices using microwave energy, called microwave energy devices, and transcranial
magnetic stimulators for the treatment of psychiatric and neurological disorders have been introduced.
Therefore, there is a need to establish compatibility between the safety of human life andelectromagnetic fields. The following is a summary of the activities of the Japanese URSI Commission
K for 2022-2023.
We have held regular meetings of the Japanese URSI-Commission K and annual scientificsymposia in this field, and have promoted activities in cooperation with various fields such as electricaland electronic engineering, medicine, and biology. In addition, we have conducted activities to gaininternational recognition for our research results through journal papers and scientific conferences.
BioEM is the world's largest conference on bioelectromagnetics, attracting academic andindustrial participants from all over the world at all career stages, and is highly regarded. The BioEM
2022 （https://www.bioem2022.org/）was held in Nagoya, Japan as a hybrid conference, with about
300 participants, and core members of the Japanese Commission K attended this conference andalso contributed as local organizing committee members.
