Research summary

MEMS/NEMS Processing Laboratory studies the basics and applications of Micro Electro Mechanical Systems (MEMS). We use advanced micro/nano-fabrication and strive to create a new value by combining “mechanical engineering” and “life science.”
Application fields are the development of MEMS devices/systems to support innovation in medicine and life science. Currently, our group focuses on three projects: (1) nano-fabrication and measurement system for a single cell, (2) cellular MEMS, and (3) microorganism-based MEMS.

環境エネルギー変換工学研究室

Research summary

This laboratory aims to develop eco-friendly combustion technology with insights into combustion science. The eco-friendly combustion technology does not only mean improvement of energy efficiency of fossil fuel power generation, but also development of fire suppression technologies. Fire suppression technologies will contribute to reduction of carbon emissions as well as improvement of energy efficiency of fossil fuel power generation, since some researchers reported that the amount of wildfire emissions of carbon is equivalent to 20% of the mean annual global carbon emissions from fossil fuels. Unfortunately, the most common cause of fires is human activity such as burning debris, unattended campfire, and so on. Both technologies for improvement of energy efficiency and fire suppression play a key role in reducing carbon emissions for a sustainable future.
