A 3D surfaces and 2D polar plots of Poisson’s ratio obtained by ELATE visualization. Blue and black lines represent the maximal and minimal positive values, respectively. The red line represents the minimal negative values over all possible values. B Top view of the atomic movement corresponding to the minimal Poisson’s ratio. The folded gray areas unfold as the stress is applied along u direction, as shown in the figure from left to right in the figure along the gray arrows. blue arrow; u = (−0.766, 0.438, 0.471) and black arrow; v = (−0.314, 0.385, −0.868) directions. C Deployable mechanism of DCS origami tessellation. Source data are provided as a Source Data file.
