| Outline of Final Research Achievements |
The peculiar motility in microbiological systems is related to the micro and nano flows. In this research, the flow mechanism of micro and nano fluid flows associated with macroscopic movement of microorganisms was investigated. In addition, the development of micro-devices based on the principle of the micro flow mechanism in biological motility system was also aimed in the research.
The results obtained are summarized as follows. The fine folding structure and active periodic motion of swimming organ in beach flea produce effective thrust in the low Reynolds number region. The leaping organ of the springtail has unique hollow pipe shape with one long groove. Compressibility of the air in leaping organ plays an important role during insect extreme long distance jump on the water surface. Movement of the flower head is accomplished by fluid flow between the petal cells. Based on the above obtained results, the micro magnetic fluid device for generating micro flow was developed.
