Biomimetic Cilia

Due to their small dimensions, microfluidic devices operate in the low Reynolds number regime. In this case, the hydrodynamics is governed by the viscosity rather than inertia and special elements have to be introduced into the system for mixing and pumping of fluids. Here we report on the realization of an effective pumping device that mimics a ciliated surface and imitates its motion to generate fluid flow. The artificial biomimetic cilia are constructed as long chains of spherical superparamagnetic particles, which self-assemble in an external magnetic field. Magnetic field is also used to actuate the cilia in a simple nonreciprocal manner, resulting in a fluid flow. We prove the concept by measuring the velocity of a cilia-pumped fluid as a function of height above the ciliated surface and investigate the influence of the beating asymmetry on the pumping performance. A numerical simulation was carried out that successfully reproduced the experimentally obtained data.

This article presents the effect of excitation waveforms on the rate of micromixing evaluated using biomimetic cilia-based microfluidic devices (soft cantilever-type, vibrating devices that are excited by the oscillations of the piezoactuator with different trajectories). The main contribution of this article is to experimentally evaluate the mixing excited by different waveforms and to report that (i) the mixing time is significantly decreased through employing the cilia when compared to the case without employing the cilia; (ii) the mixing time in case of employing the cilia is additionally decreased through the application of the symmetric triangular waveform with sharper turnarounds when compared to the case of the symmetric sinusoidal waveform (with smoother turnarounds); (iii) furthermore, the mixing time in case of employing the cilia is reduced further through applying asymmetric excitation waveforms with greater asymmetry when compared to the case of applying asymmetric excitation waveforms with less asymmetry.
