Abstract: A chemo-mechano-chemical (C1-M-C2) system includes a base supporting an actuatable structure, said structure comprising a functionalized portion and being embedded in an environmentally responsive gel capable of volume change in response to an environmental stimulus; a first fluid layer disposed over the base and in contact with the actuatable structure, said first fluid layer comprising the environmentally responsive gel; and a second fluid layer in contact with the actuatable structure, wherein the layers are positioned such that the functionalized portion is in contact with the second layer in a first relaxed state and in contact with the first layer in a second actuated state and wherein the functionalized portion interacts with at least one of the layers to provide a chemical or physical response.

Abstract: A document and an Anti-counterfeiting method for use in such documents are described. Said document and Anti-counterfeiting method include introducing a plurality of raised nanoscopic to microscopic structures, here referred to as reconfigurable structures, formed over a polymer substrate to induce optical changes, such as structural color and/or optical fuzziness. Dynamic changes using liquids provide the anti-counterfeiting measures.
