Abstract
Systems in one embodiment of the present invention comprise rotating element sheet material with a microstructured substrate component, and a method of assembling such rotating element sheet material. A first embodiment of the present invention comprises a substrate, enabling fluid, a plurality of rotatable elements of a first class, and a plurality of rotatable elements of a second class, where the substrate comprises a cavity-containing matrix having a plurality of cavities of a first class and a plurality of cavities of a second class, where the plurality of rotatable elements of a first class are disposed within the plurality of cavities of a first class, and the plurality of rotatable elements of a second class are disposed within the plurality of cavities of a second class, and where the plurality of cavities of a first class and the plurality of cavities of a second class are arranged in a regular, repeating pattern in a substantially single layer, or alternatively, the plurality of cavities of a first class and the plurality of cavities of a second class are arranged to define macroscopic regions displaying common aspects. A further embodiment of the present invention inclu…
