1. A method of manufacturing an auxetic stretchable substrate with a flexible joint structure, the method comprising:
preparing a substrate made of an elastic material; and
forming an auxetic to form a plurality of first regions on the substrate,
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 plurality of first regions have different lengths.
