Computational Design of Magnetic Artificial Cilia
View through CrossRef
Micron‐scale fluid propulsion takes place in nature using hair‐like motile appendages known as cilia. In this work we design artificial cilia that can be realized using thin films consisting of a polymer matrix filled with magnetic nanoparticles, so that they can be actuated using an external magnetic field. We use a coupled magneto‐mechanical solid–fluid numerical model to find under what conditions a magnetic film will mimic the asymmetric motion of natural cilia. The fluid propelled, and the pressure generated by the artificial cilia, are further studied in terms of the dimensionless parameters that govern their physical behaviour and identify the parameter space in which the cilia can generate maximum fluid transport.
