Breaking of symmetry in microfluidic propulsion driven by artificial cilia.

In this Brief Report we investigate biomimetic fluid propulsion due to an array of periodically beating artificial cilia. A generic model system is defined in which the effects of inertial fluid forces and the spatial, temporal, and orientational asymmetries of the ciliary motion can be individually controlled. We demonstrate that the so-far unexplored orientational asymmetry plays an important...

Emergence of metachronal waves in cilia arrays.

Propulsion by cilia is a fascinating and universal mechanism in biological organisms to generate fluid motion on the cellular level. Cilia are hair-like organelles, which are found in many different tissues and many uni- and multicellular organisms. Assembled in large fields, cilia beat neither randomly nor completely synchronously--instead they display a striking self-organization in the form ...

Magnetically actuated artificial cilia for optimum mixing performance in microfluidics.

Contemporary lab-chip devices require efficient, high-performance mixing capability. A series of artificial cilia with embedded magnetic particles was fabricated to achieve precise flow manipulation through magnetically driven control. These fabricated structures were actuated in a homogeneous magnetic field generated by a built-in magnetic coil system for various beating cycles inside a microc...
