In his Review @ RRL (article no. 1600440 ), Teik‐Cheng Lim establishes analogies across auxetic models by identifying mechanism similarities. On the cover, the identification of auxetic mechanism analogy from four models is shown: the rotating square model (top left), anti‐tetrachiral model (top right), a type of missing rib model (bottom left), and re‐entrant model (bottom right). One quadrant from each auxetic model, consisting of four rotating elements, is transposed onto corresponding quadrants in the other auxetic models to show the analogous counterparts. Likewise, the color‐coded circles or linkages in the top right quadrants indicate the corresponding joints. The mechanism analogy across different auxetic models reveals that it is the mechanism comparability, rather than geometrical resemblance, that takes precedence in establishing fundamental similarities across various auxetic models. Consequently, any newly introduced auxetic model would be classified as being of only incremental advancement, even if it exhibits novelty in geometrical microstructure, as long as its deformation mechanism is well‐established. The demonstration of a new deformation mechanism would be required to justify the classification of any introduced auxetic model as being fundamentally novel.
