  • This thesis presents the details behind the production of a novel biomimetic cilia system which will be useful in exploring the detailed mechanisms of fluid flow generation in biological cilia systems. The biomimetic system consists of an array of flexible, high-aspect-ratio magnetic structures of the same size as biological cilia, and is actuated by magnetic fields. First, I will describe the array of materials which are available for use in this system, including a couple of novel materials which I have designed for this work. Next, I will describe the steps necessary to fabricate large arrays of microscale biomimetic cilia with these materials. I will then formulate a mathematical model to predict the bending of these structures in an applied magnetic field, and demonstrate how this model is helpful in designing a biomimetic cilia system. Finally, I will describe several modes of actuation which are predicted by the model and have been verified by experiment in the biomimetic system, and discuss the biological relevance of these modes of actuation.
