NIMS has created and started its Center for Functional Sensor & Actuator (CFSN) from 2018 with the view to develop materials and systems for sensors and devices which can enable the realization of Society 5.0. One very important research goal is to develop technology which can dynamically energy harvest from surroundings to power maintenance-free sensors and devices. This session will invite world-wide leading experts from the field to deliver invited talks and discussion on this important topic.

Speakers

Yuji Suzuki
Professor, Department of Mechanical Engineering, The University of Tokyo, Japan
Dr. 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 served as the general co-chair of IEEE MEMS2010 (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.
"Electret-based Energy Harvesting for Wearable Devices"
Energy harvesting from human walking is suitable for powering battery-less wearable devices. In such applications, rotational energy harvesters (EHs) have advantages over vibration EHs due to the fact that low-frequency 3-D vibration with 3-axis rotation is dominant. Among various transduction mechanisms, electret generators are advantageous in terms of higher output power at low frequencies and their low-profile structures. In this talk, developments of new electret material and their application to rotational electret EH are introduced.
Peter Franz Rogl
Univ. Prof. iR., Institute of Materials Chemistry University of Vienna, Wien, Austria
Dr. Peter Rogl is oUniv. Prof. at the Institute of Materials Chemistry of the University of Vienna, Austria. He received his PhD from the University of Vienna in 1971 followed by a postdoctoral period (1974 -1976) at the Oregon Graduate Center for Study and Research, Portland, Oregon, USA. Since 2004 he is a Full Professor for Advanced Materials at the Faculty of Chemistry of the University of Vienna. During the last years he was engaged in thermoelectrics (clathrates, skutterudites, half Heusler compounds) and together with TIAG AG, Austria has developed a large scale fabrication process for high efficiency and long-term reliable skutterudite thermoelectrics.

"HALF HEUSLER THERMOELECTRICS WITH HIGH TE EFFICIENCY"
The Half-Heusler thermoelectric materials have the potential for low-cost, high temperature and high-efficiency thermoelectric power generation.
Fabien Grasset
Senior Researcher, National Centre for Scientific Research (CNRS), France UMI3629, LINK, Japan
Dr. Fabien Grasset is senior research scientist at the French National Centre for Scientific Research. He is currently director of the international research laboratory LINK, (Laboratory for Innovative Key Materials and Structures-UMI 3629), in partnership between NIMS, CNRS and Saint-Gobain based at Tsukuba in Japan. In 1998, he received his Ph.D. degree in solid state chemistry from the University of Bordeaux, France. After a postdoctoral tenure at Institute of Condensed Matter Chemistry (ICMCB) on magnetic nanoparticles for nanobiotechnology, he undertook a postdoctoral fellowship (STA grant, 2000-2001) on functional SiO2 nanoparticles at the National Institute for Materials Science (NIMS) in Japan. Soon after his tenure in Japan, he was appointed as an Associate Professor in the University of Rennes 1 (UR1), France, where he extensively worked on colloidal chemistry and development of nanomaterials at the UMR 6226 ISCR until September 2014. Finally, he joined CNRS in October 2014 as Director of Research. His key research focus is on the synthesis of new functional colloidal nanostructure (M@ZnO, M@SiO2, and γ-Fe2O3) and thin film nanocomposites. Since 2006, he extended his knowledge on nanocomposite materials based on transition metal atoms clusters. In 2007, he was invited for 3 months, as a short-term fellow of the International Center for Young Scientist (ICYS) at the NIMS. From 2007 to 2009, he was PI of a MERLION PHC between the National University of Singapore and the UR1 1. In 2008, he was elected to the National Committee of CNRS (section 15) and he served in that position till 2012. From 2011-2019, he was a PI in 4 ANR’s projects. He is currently the editorial board member of Science and Technology of Advanced Materials and Heliyon.
"TRANSPARENT NANOCOMPOSITES AND COATINGS FOR PHOTOCONVERSION APPLICATIONS"
Over the last years, transparent thin films or coatings are of a great interest as they can be used for the elaboration of smart windows or transparent photovoltaic. Notably, research is focused on robust, low cost and highly transparent functional nanocomposite thin films for photoconversion applications. The applications of these films consist of light and color devices, photovoltaic solar concentrators and window solar control.
