dc.description.abstract Biological cilia can sense minute chemical variations or the presence of particulates in their environment, transmit this information to their neighbors, and thereby produce a global response to a local change. Using computational modeling, we demonstrate two distinct examples of analogous sensing and communicating behavior performed by artificial cilia. In the first example, cilia formed from chemo‐responsive gels undergo the oscillatory Belousov–Zhabotinsky (BZ) reaction. The activator for the reaction, u, is generated within these BZ cilia and diffuses between the neighboring gels. By varying the spatial arrangement of the BZ cilia, we not only alter the directionality of the traveling waves within the array, but also uncover a distinctive form of chemotaxis, where the tethered gels bend towards higher concentrations of u and, hence, towards each other. We also show that the cilial oscillations can be controlled remotely and non‐invasively by light. In our second example, we model the transport of a microscopic particle via a regular array of beating elastic cilia, whose tips experience an adhesive interaction with the particle’s surface. By varying the cilia–particle adhesion strength and the cilia stiffness, we pinpoint the parameters where the particle can be ‘released’, ‘propelled’ or ‘trapped’ by the cilial layer. en_US
