Auxetic scaffolds were prepared successfully by using the volumetric restricted method.
The recovery rate of the auxetic scaffold specimens increased with increasing loading time (Figure 5).
The study investigated MG-63 osteoblast-like cell proliferation on auxetic scaffolds under static and dynamic compressive stimulation conditions.

Hence the reentrant honeycomb deforming by rib hinging is an auxetic structure.
Reentrant cell geometrical parameters, that is, H, L, and A, can even change the sign of Poisson's ratio from negative to positive, when auxetic honeycombs bear a Y-direction tensile loading or an X-direction compressive loading, where H is the vertical length of the cell member, L is the inclined length of cell member, and A is the angle between undeformed inclined cell member and X-axis (in Figures 2 and 3).
In all of the auxetic materials there is a specific microstructure that is vital to creating a negative v, deformation mechanism like rib hinging, bending or stretching, and rotating, and so forth.
In some cases, the presence of auxetic behaviour in very different systems has been explained by using the same deformation mechanism, for instance, "the rotation of rigid units model has been used to account for the auxetic behaviour in materials ranging from silicates and zeolites (where the auxetic effect is due to nanostructure of the materials) to polymeric foams (where the auxetic effect is due to features at the micromillimeter scale) and macrostructures [7].
Auxetic materials are of interest because of the novel behaviour they exhibit under deformation and also because many other materials properties can be enhanced as a result of having a negative v.
Auxetic ultra high molecular weight polyethylene (UHMWPE) exhibits enhanced indentation resistance by up to a factor of three when compared with conventional UHMWPE and enhanced attenuation of ultrasonic signals [2,3].
