Presentation Title:

Development of flexible sheet imaging sensor for IoT

Time: TBD

Presentation Abstract:

A flexible device is expected to be one of the most attractive human-machine interface devices due to its high usability. Therefore, there is growing interest in the development of new flexible devices such as flexible displays, sensors, and circuit board, now a days. In this study, we have developed a flexible sheet sensor, especially imaging sensor for detecting several distribution data of physical signals such as pressure, temperature, gas flow on a soft and/or curved substrate. The developed sensor is consisting of highly integrated sensor arrays prepared on a film substrate. Each sensor is driven by TFT, therefore distribution data of physical signal from the flexible sheet sensor can be detected as mapping data. In order to prepare such a highly integrated sensor arrays, we have developed low- temperature, and low-damage flexible device manufacturing technology based on the printing technology. Especially, fine patterning with high resolution is one of the unique and characteristic point of this newly developed method. In this presentation, we will show several our developed flexible imaging sensors.


Toshihide Kamata received a PhD from Kyoto University in 1991. He joined National Institute of Advanced Industrial Science and Technology (AIST) in 1992. He is currently Director of Flexible Electronics Research Center of AIST, and professor of Tsukuba University. He is also R&D director of JAPERA (Japan Advanced Printed Electronics Research Association). His research interests have been in the flexible & printed electronics and display, sensor technologies.
