Kirigami Structure with a Large Uniform Deformation Region

We proposed a new kirigami structure with large area of uniform deformation during stretching deformation. Our proposed kirigami structure in which both ends are deformed from a rectangular to a trapezoidal shape, and almost all the region are uniformly deformed. In order to evaluate the ratio of uniform deformation region, measuring the each area of open cuts of the kirgami structure under stretching deformation. As a result, the ratio of the uniform deformation region is 36.1% in the normal (conventional) kirigami structure is 97.5% in our proposed kirigmai structure, increased the uniform deformation region by 270%.
