Team Daisuke +R, a team led by Daisuke Yamaguchi (2nd year, Graduate School of Science and Engineering Master’s Program), took home the second place prize in the WPT Track of the Student and Young Engineer Design Competition at the 2022 Asia-Pacific Microwave Conference (APMC), which was held at Pacifico Yokohama from Tuesday, November 29 to Friday, December 2, 2022.

The APMC is a global academic conference dedicated to the advancement of microwave engineering and technology in the Asia-Pacific region. The Student and Young Engineer Design Competition is a video competition for young researchers and engineers under the age of 38 that aims to encourage their participation in the research and development of wireless power transfer technology (WPT).
Yamaguchi’s team competed in the WPT Track. Based on the topic of how WPT will change our lives, each team gave a video presentation on their research on WPT applications, which have the potential to improve our lives in the future.

Yamaguchi’s team presented the outcomes of their research on a three-story model railroad they created using WPT. By using rails mounted with tiny circuit boards as power transmission antennas, and by applying innovations to optimize power transmission performance, the team designed the model so that power could be supplied to the second and third-story rails by only feeding power to the rails on the first story.
The outcomes of this research hold promise for their commercial application to WPT-driven model trains. In the video competition, Yamaguchi’s team won the top scores for the originality and clarity of their research, and their presentation techniques and video editing were also highly rated.

Comment from Daisuke Yamaguchi (2nd year, Graduate School of Science and Engineering Master’s Program)


My team was able to take home the second place prize in the WPT Track of this year’s Student and Young Engineer Design Competition. I would like to take this opportunity to thank our supervisors, Professor Takakuni Douseki, Lecturer Ami Tanaka, and Visiting Professor Hisashi Nishikawa as well as everyone in our lab who helped us in many ways.
When I first entered the graduate school, my grades were poor and I could not keep up with the research, but my life changed forever when I met my labmates and was introduced to the model railroad research project. I learned first-hand that just being able to study does not necessarily mean you will be able to conduct research, and I am grateful for this opportunity.
In this research project, I was able to take full advantage of board fabrication skills I had learned by participating in a soldering contest held by Professor Douseki as well as the video editing skills I had honed as a hobby. We would not have been able to win this prize if any of these elements, including the support of everyone in my lab and my encounter with this research, had been missing. Thank you very much.
