Abstract
An artificial cilium device includes a substrate and a voltage-actuated cilia-shaped structure attached at a proximal end to the substrate. The voltage-actuated cilia-shaped structure has a first layer of a first material and a second layer of a second material. The second layer of the second material includes an exposed surface that causes the cilia-shaped structure to, in a working medium, (a) change shape from a first shape to a second shape responsive to application of a first voltage and (b) change shape from the second shape to the first shape responsive to application of a second voltage different than the first voltage.
