About us

Specific mechanical properties of nano- and micro-materials are revealed through world-class experimental techniques using the latest experimental equipment.


In this laboratory, we are studying on the mechanical properties of nano- and micro-sized materials.
Nano/micro-sized materials are widely used in various advanced electronic devices and sensors, and their unique mechanical properties have unlimited potential to create new functions that have never existed before. However, in order to realize a convenient, safe, and secure society, it is necessary to elucidate their mechanical properties, many of which are still unknown.
In particular, we are interested in the characteristic strength and fracture behaviors of nano- and micro-sized materials, and the emergence of unique physical properties under mechanical loading. We conduct everything from the design and fabrication of samples to microscopic loading experiments in transmission electron microscopes and scanning electron microscopes, as well as numerical and theoretical analysis. We also actively collaborate with other universities, research institutes, and industry to produce cutting-edge research results, and also focus on education so that we can send students out into the society with sufficient ability and knowledge.
Our laboratory provides an environment in which students can concentrate on their research. It is a place where students can challenge themselves based on their own ideas, free from preconceived notions, while sharing accumulated knowledge. We welcome all motivated students to join our research group.

Features of our laboratory

Latest research equipment
We have a variety of high-end microscopes that are necessary for the observation of nano- and micro-sized materials, as well as micromachining and deposition equipment used for sample preparation. For loading devices, we design and develop new devices to perform mechanical experiments that are completely unique in the world. In addition, we can conduct the world's most advanced research using various analytical software and analytical equipment.
Collaboration with Industry
Our laboratory has experience in joint research with companies in the materials, electrical, automotive, and other industries, and we are still receiving requests from several companies. Students participating in joint research are encouraged to actively participate in meetings with corporate researchers and engineers, so that they can acquire presentation and communication skills that will be useful after graduation.
Education of young researchers and engineers
While our research activities are aimed at providing the world's most advanced results, we also provide guidance to students with the goal of helping them acquire the "abilities necessary after graduation". We encourage discussions not only with faculty members but also among students to improve their individual abilities. We also invite researchers from abroad and accept international students, and create an environment that nurtures young researchers and engineers with global competence.


Open Lab

We provide opportunities for students to visit our laboratory and deepen their understanding of our research.

Seminar (presentation of research)

Laboratory-wide research meetings are held once a half year. Meanwhile, from time to time, discussions and lecturing in turn are held within individual research teams.
