The aim of this Research Area is to create innovative core technologies for converting heat, light, vibration, electromagnetic field, biological body, and other types of ambient microenergy into electricity in the range of μW~mW for use in self-powered sensors, microprocessors, and other types of devices.
More specifically, research will be promoted along two principal lines. One will focus on the development of core technologies and their underlying basic principles, for the highly efficient conversion of ambient microenergy produced from heat, light, vibration, electromagnetic, biological body, and other forms of energy sources. This is research that will develop substances and devices to convert untapped microenergy into electricity based on the new principles. It will be the challenge of discovering new principles contributing to innovative energy conversion such as that utilizing spin correlations or topological correlated phases and developing new materials with physical properties far surpassing the characteristics of substances to date. The other principal line of research will be on theories, analytical evaluation, and material design for developing the core technologies mentioned above. This research will attempt to develop new analytic formulations for the physical phenomena (properties of materials and interfaces, transport phenomena, etc.) that come into play in energy conversion, and will put forth guidelines for new-material design based on condensed matter physics or applying computer simulation. It is extremely important to pursue these two principal lines of research in closely collaborative and mutually complementary ways.
Accordingly, this Research Area calls for highly challenging proposals, which pursue to produce innovative principles, substances and devices to be tested and verified in their final stages, and which will lead to follow-on research and development stages.
This Research Area, therefore, will be an integrated CREST/PRESTO where work will be pursued under the strong leadership of the Research Supervisor and Deputy Research Supervisor, and efforts will be made to reorganize research teams, coordinate research programs, and promote strong communication among researchers pursuing different themes, all for the maximization of research achievements.
