Cils artificiels: modèle physique pour la propulsion ciliée

Abstract : Most microorganisms use cilia or flagella as a means of propulsion. These low Reynolds number swimming mechanisms have been studied theoretically and experimentally on living organisms. However, so far very few physical experimental models have been realised. We describe here the fabrication of microscopic artificial cilia, actuated by a magnetic field. These artificial cilia share with real cilia a large aspect ratio, great flexibility, and the actuation by a magnetic torque distributed along thier full lenght. We studied the planar and three-dimensional beatings of these magnetic cilia. We also characterized the forces and flows induced in the surrounding fluid.
