Abstract
A product includes a three-dimensional structure having a plurality of sequentially-formed layers comprised of liquid crystal elastomers. The liquid crystal elastomers in a portion of a first of the layers are substantially aligned in a predefined first orientation and the liquid crystal elastomers in a portion of a second of the layers are substantially aligned in a predefined second orientation that is different than the first orientation. Each of the portions of the three-dimensional structure is characterized as exhibiting a shape change in response to a stimulus, wherein the shape change is reversible. The product includes a contiguous region of aligned liquid crystal elastomers in one of the portions having a maximum dimension of less than 60 microns.
