Omori Lab
Machine-translated · View original
A biofluid mechanics lab that unravels the flows related to living things through the lens of mechanics.
AboutAbout the lab
Unraveling the flow of life
The biofluid mechanics group (Ishikawa/Kikuchi/Omori Lab) uses biomechanics to study the physiology and pathology of the blood circulatory, respiratory, and digestive systems, among others.
While studying flows related to living things, such as the flight of birds and the swimming of fish, the lab focuses on the flow and rheological properties of suspensions containing many small swimmers.
Its research is presented in the fields of medicine, fluids, the environment, robotics, food, biology, and evolution.
The lab is affiliated with the Graduate School of Biomedical Engineering and the Department of Finemechanics in the Graduate School of Engineering at Tohoku University.
Key terms
- Biomechanics
- A field that studies the movements of the bodies and cells of living things, and flows inside the body, using concepts of mechanics
- Suspension
- A liquid in which particles or small swimmers are mixed. This lab studies suspensions containing many swimmers
- Rheology
- The properties of how a material flows and deforms. Viscosity is one of them, and the lab studies it together with the flow of suspensions
- Active fluids
- Fluids containing swimmers that move around on their own. Unlike suspensions of passive particles, they show unusual properties, such as negative viscosity

ResearchResearch themes
The biofluid mechanics group studies flows related to living things from the viewpoint of mechanics. In the fields of medicine, fluids, the environment, robotics, food, biology, and evolution, it investigates biological phenomena and the behavior of microorganisms.
*Illustrative imageBiomechanics for Medicine
The lab uses biomechanics to study the physiology and pathology of the blood circulatory, respiratory, and digestive systems, among others. 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, and the lab studies them as active fluids.
*Illustrative imageThe Role of Microorganisms 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 imageHow Microrobots Propel Themselves
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.
