Abstract
Disclosed is a zero Poisson's ratio structure including a central pillar; at least two branched connectors extending radially from a lower end of the central pillar, wherein each of the branched connectors includes: a first segmental portion extending inclinedly upwardly or downwardly from the central pillar; and a second segmental portion extending inclinedly downwardly or upwardly from a distal point of the first segmental portion, wherein the extension directions of the first and second segmental portions are opposite to each other; and each leg extending perpendicularly downwardly from a distal point of each of the second segmental portions, wherein due to a force pressing the central pillar, each of an angle between the central pillar and the first segmental portion, an angle between the first segmental portion and the second segmental portion, and an angle between the second segmental portion and the leg is variable.
