We have started to use "Twitter" to introduce our research activities! Follow us!
Our research focuses on micro/nanomaterial integrations based on electrical, material, mechanical, and neural engineering. The contributions of the research are “translational nanotechnology” to show the possibilities of a combination of top-down and bottom-up nano/micro materials and their device integrations. Our principal achievements are 1) CMOS/MEMS neural devices, 2) high-performance transistors on Si and their device physics, 3) macroscale flexible electronics for flexible, high-performance, and low-power electronics, 4) human-interactive wearable devices, and 5) brain machine interfaces.
If you would like to admit Osaka Metropolitan University and join our group, please submit your application as you can find more detail here "Admission guidelines for international students". Application deadline is June and December for admission in October and April, respectively. Also there are some scholarships for the international students to support tuition and living cost. For more detail, please contact to Prof. Takei.
If you are interested in this group to work together as a postdoctoral fellow, there is a postdoctoral fellowship program for foreigners supported by Japan Society for the Promotion of Science. We also accept talented visiting students/researchers as well. Please email your CV to Prof. Takei.
