It is like when you press a rubber ball, it flattens out sideways, and when you pull a rubber band, it stretches tightly.<\/p>\n<p>The amount of transversal elongation divided by the amount of axial compression is Poisson\u2019s ratio. Conversely, mechanical metamaterials, unlike materials in nature, are artificially designed to expand in both the horizontal and vertical directions when it is stretched in the horizontal direction.
