Abstract
The working mechanism of cilia comprises an effective and a recovery stroke that are different in nature. This unique asymmetric motion of the cilia is an essential feature to generate net fluid flow at low Reynolds numbers. Inspired by this asymmetric mechanism, thin-film artificial cilia have been fabricated to propel fluids in the microchannels of lab-on-a-chip biosensors. The artificial cilia are polymer films embedded with magnetic nanoparticles and are actuated by an external magnetic field, mimicking the beating of natural cilia. In this chapter, we describe the basic results obtained from an extensive numerical analysis of generating fluid transport using magnetically driven artificial cilia.
