研究の背景 Background


In the near feature, the various information of real space will be spread over cyber space through cyber physical system (CPS), which will promote the efficiency of every social system. In order to realize the matured CPS, the development of electric devices for the interface between the real and cyber space is very important. In the next-generation electronic devices, it is needed to consider their diverse functionalities and environmental sustainability, such as low-power consuming, low cost fabrication and large-area processability.

研究の目標 Outcome


In this research, the main interest is a development of technology and understanding of fundamental physics for organic semiconductors, which has unique functionalities such as low-cost fabrication process and good mechanical flexibility. The object of this research includes the development of application system such as wearable medical diagnosis devices and wireless sensor systems for infrastructures.
