负泊松比行为已被发现在蜂窝固体，包括一个固体基质与一个正方形阵列的圆形空隙。制造的简单性意味着稳健的行为，这在一定范围的尺度上是相关的。该行为的结果从弹性不稳定，诱导模式转换和良好的定量计算和实验之间的协议。
Negative Poisson's ratio behavior has been uncovered in cellular solids that comprise a solid matrix with a square array of circular voids. The simplicity of the fabrication implies robust behavior which is relevant over a range of scales. The behavior results from an elastic instability which induces a pattern transformation and excellent quantitative agreement is found between calculation and experiment.
