Patent ID: 7501069

Claim:
A method of making a free-standing structure, said method comprising the steps of: providing a substrate; providing a first sacrificial layer on the substrate; providing a first patterned structural layer comprising a plurality of first structural elements on said first sacrificial layer, wherein the first structural elements are not in direct physical contact with each other, have inner surfaces in contact with the first sacrificial layer and have outer surfaces opposite to said inner surfaces; providing a second sacrificial layer on the first patterned structural layer; removing material from selected regions of said second sacrificial layer thereby forming a plurality of removal spaces in the second sacrificial layer that provides at least one exposed region of the outer surface of each of the first structural elements; providing a second patterned structural layer comprising a plurality of second structural elements on said second sacrificial layer, wherein the second structural elements are not in direct physical contact with each other, and wherein at least one second structural element contacts at least one exposed region of the outer surface of each of the first structural elements; and removing the first and second sacrificial layers, wherein removal of the first and second sacrificial layers releases the first and second patterned structural layers and generates said free-standing structure comprising interlocking assemblies of interconnected first and second structural elements, and wherein said interlocking assemblies of the interconnected first and second structural elements are independently displaceable; wherein the free-standing structure comprises a fabric, wherein said interlocking assemblies of the interconnected first and second structural elements comprise elements of said fabric.
