Abstract
An auxetic polygonal cell may have a plurality of chiral structures capable of rotation. The plurality of chiral structures may at least partially enclose a volume. Each of the chiral structures may include a first cross member having a first set of distal ends and a second cross member intersecting the first cross member, the second cross member having a second set of distal ends. The chiral structures may also include a first set of legs, wherein each leg of the first set of legs extends from at least one distal end of the first set of distal ends and a second set of legs, wherein each leg of the second set of legs extends from at least one distal end of the second set of distal ends.
