l   演講內容

Energy harvesting from human motion is suitable for powering battery-less wearable devices. In such applications, electret energy harvesters (EH) have advantages over other type of EHs due to the fact that low-frequency motion is dominant. In this talk, development of new electret materials based on quantum chemical analysis and machine learning are presented, and their application to rotational/stretchable electret EH are introduced.

In the last 90 years since the first development of electret using Carnauba wax, electret materials have been developed by heuristic approach. In the present study, for the first time, a novel high-performance amorphous fluorinated polymer electret based on quantum chemical analysis and machine learning is proposed. A new electret material based on CYTOP thus obtained offers a record-high surface charge density with extremely-high thermal stability of implanted charges. In addition, novel stretchable electret material based on amorphous fluorinated polymer is also discussed.

As an application of the developed CYTOP electret, a novel low-profile rotational electret EH is prototyped. Output power up to 1 mW has been obtained at a low rotational speed of 1 rps with only 3 mm in thickness. Evaluation of the rotational EH for human walking is also discussed.

l   講員簡介

   Prof. Yuji Suzuki received the B.S., M.S., and Dr.Eng. degrees in mechanical engineering from the University of Tokyo, Tokyo, Japan, in 1987, 1989, and 1993, respectively. He is currently with the Department of Mechanical Engineering, the University of Tokyo, as a Professor. He received IEEE Fellow, Fellow of Combustion Institute, and Fellow of JSME. He serves as Steering Committee Member of PowerMEMS Conference, Organizing Committee member of IEEE International Symposium on Electret (ISE). He also served as the general co-chair of IEEE MEMS 2010 (Hong Kong) and the general chair of PowerMEMS 2017 (Kanazawa). His research interests include MEMS-based energy harvesting using electrets, micro energy conversion such as microscale combustion, and optimal design/control of micro heat and fluid flow.
