Research Content

Micro Electro Mechanical Systems (MEMS), which are “tiny machines”, are used in various places such as accelerometers in smartphones and micromirror arrays in projectors. In a small world of several tens of nanometers to several hundreds of micrometers, the influence of frictional force is greater than the force of gravity, and light interacts with structures with a size of the wavelength of light. By actively using these effects, we are conducting extensive research on assembly technology for microstructures and sensors and actuators using microstructures.

A Brief Comment

Tiny machines such as MEMS and large machines such as aircraft may be the same in some aspects or completely different in certain aspects in design, production, use and evaluation. For example, even if a large machine structure is made with the dimensions reduced as it is, it may not move at all. Let's try new and interesting research by understanding and using what is the same and what is different.
