Kikuchi Lab
Machine-translated · View original
A biofluid mechanics lab that uses mechanics to explain the flows related to living things.

AboutAbout the lab
Unraveling the flow of life
The Kikuchi Lab studies biological fluid mechanics, which deals with flows related to living things, such as the flight of birds and the swimming of fish.
It presents research that applies biomechanics across a wide range of fields, from medicine and food to the evolution of living things.
On the lab's website, it is presented under the name "Ishikawa/Kikuchi/Omori Lab" as the biofluid mechanics group of the Graduate School of Biomedical Engineering and the Graduate School of Engineering.
Key terms
- Biological fluid mechanics
- A field that studies flows related to living things, such as the flight of birds and the swimming of fish
- Active fluids
- Suspensions containing many small swimmers that move around on their own. They show unusual properties, such as negative viscosity
- Microswimmers
- Microscopic objects that swim on their own. This lab studies ones with soft membrane structures

ResearchResearch themes
The lab uses biomechanics to study a variety of flows and biological phenomena related to living things. Its research is presented in the fields of medicine, fluids, the environment, robotics, food, biology, and evolution.
*Illustrative imageMedicine and Biomechanics
The lab uses biomechanics to study the physiology and pathology of the blood circulatory, respiratory, and digestive systems. Its research on sperm behavior provides basic knowledge about fertilization and infertility, and it also works on developing medical devices in collaboration with medical schools.
*Illustrative imageResearch on Active Fluids
The lab focuses on suspensions containing many small swimmers and studies their flow and rheological properties. Because the swimmers move around on their own, these suspensions show unusual properties, such as negative viscosity.
*Illustrative imageMicroorganisms and Mass Transport in the Environment
The lab studies the role microorganisms play in mass transport, such as in water purification. For harmful red tide algae, it investigates the mechanism by which red tides form in ocean turbulence, in collaboration with the Japan Fisheries Research and Education Agency.
*Illustrative imagePropulsion of Microrobots
Drawing on knowledge gained from the swimming of microorganisms, the lab studies the mechanisms by which self-propelled particles, such as microswimmers with soft membrane structures and Janus particles, propel themselves through complex environments such as blood.
