  • Swimming like algae: biomimetic soft artificial cilia

Sareh, Sina, Rossiter, Jonathan, Conn, Andrew, Drescher, Knut and Goldstein, Raymond, 2012, Journal Article, Swimming like algae: biomimetic soft artificial cilia Journal of the Royal Society Interface, 10 (78). pp. 1-12. ISSN 1742-5662

Abstract or Description:

Cilia are used effectively in a wide variety of biological systems from fluid transport to thrust generation. Here, we present the design and implemen- tation of artificial cilia, based on a biomimetic planar actuator using soft- smart materials. This actuator is modelled on the cilia movement of the alga Volvox, and represents the cilium as a piecewise constant-curvature robotic actuator that enables the subsequent direct translation of natural articulation into a multi-segment ionic polymer metal composite actuator. It is demonstrated how the combination of optimal segmentation pattern and biologically derived per-segment driving signals reproduce natural cili- ary motion. The amenability of the artificial cilia to scaling is also demonstrated through the comparison of the Reynolds number achieved with that of natural cilia.
