Nanometrix Engineering

We are studying nano / micro electromechanical systems which range from fabrication and characterization of thin film materials to devise design and their optimization. In particular, we carry out several projects ; micro-TAS for bio-medical applications, analysis of complex field of dynamics, fluidics and electro-magnetics, and physiological simulation.

Hidetoshi KOTERAProfessor (Graduate School of Engineering)


My research is fabrication of micro-devices using nanometer-controlled materials and the optimal design of them using computer simulation. Both of experimental and simulation studies are carried out and their applications are ranging from electronics to bio-medical field. At present, I'm engaged in the national leading project of development of "Implantable Hospital Devices", and promote the fusion of different field as well as business-academia collaboration through this project.

Ryuji YOKOKAWAAssociate Professor (Graduate School of Engineering)


We are investigating interdisciplinary researches between micromachining and biotechnology. One of topdown technology, micromachining (MEMS), is able to fabricate nano-scale structures. Bottomup technology, here biotechnology, established a system to obtain a designated nano-scale protein based on genetic engineering. These technologies can be integrated at nano-scale to explore a novel nanodevices.
One of our research projects is to produce a bio-hybrid nano system in which biomolecular motors work as actuators. Since biomolecular motors such as actin-myosin, kinesin-microtubule, Fo/F1-ATPase etc. are of nanometers in size, they can be utilized as nano-scale actuators in MEMS/NEMS devices.
We are also interested in a microfluidic device, i.e. Micro Total Analysis Systems (uTAS). Especially, dielectrophoresis (DEP) and electro osmotic flow (EOF) are utilized to manipulate biomolecules and cells for their active manipulation.

Hirofumi SHINTAKUAssistant Professor (Graduate School of Engineering)


We actively study problems involving fluid dynamics and transport phenomena in micro/nano confined space. The problems are inspired by microfluidic systems for biochemical analysis and cellular engineering. Especially, we are interested in electrokinetic phenomena, e.g., electrophoresis, electroosmotic flow, and electrowetting, of complex fluids including cells and biomacromolecules. We use various approaches of experiments, numerical simulation, and modeling to explore the problems. Optical flow observation based on micro-PIV (particle image velocimetry), high precision current/voltage measurement, and microfabrication are major methods in experiments. Theoretical and numerical analyses based on fluid mechanics are used to understand the physics underlying the phenomena observed in experiments.
