Abstract: Disclosed herein is a method of manufacturing an auxetic stretchable substrate with a flexible joint structure. The method includes preparing a substrate made of an elastic material, forming an auxetic to form a plurality of first regions on the substrate, and forming flexible joints in each of the plurality of first regions, wherein each of the plurality of first regions is a region in which a material constituting the auxetic is not printed, and at least some of the flexible joints formed in each of the plurality of first regions have different Young's moduli.
