Magnetically-actuated artificial cilia for microfluidic propulsion [PDF]
Lab on a Chip, 2011 In this paper we quantitatively analyse the performance of magnetically-driven artificial cilia for lab-on-a-chip applications. The artificial cilia are fabricated using thin polymer films with embedded magnetic nano-particles and their deformation is studied under different external magnetic fields and flows.

Nature-inspired microfluidic propulsion using magnetic actuation [PDF]
Physical Review E, 2009 In this work we mimic the efficient propulsion mechanism of natural cilia by magnetically actuating thin films in a cyclic but non-reciprocating manner. By simultaneously solving the elasto-dynamic, magnetostatic and fluid mechanics equations, we show that the amount of fluid propelled is proportional to the area swept by the cilia.
