Abstract

Eukaryotic flagella possess 2 singlet microtubules and 9 outer doublet microtubules. Protuberances of protein called dyneins are placed along doublet microtubules to produce sliding of doublet microtubules. Bending of flagella is generated by the active sliding of doublet microtubules. We made an artificial propulsion mechanism in water imitating active sliding between 2 doublet microtubules in flagella. Electromagnets corresponding to the function of dyneins were placed along 2 flexible beams. Cyclic 2-dimensional bending movement and thrust force of the propulsion mechanism were generated in water. We discussed thrust forces of the propulsion mechanism.
