Abstract
Disclosed is a method of manufacturing a stretchable substrate according to various embodiments of the present disclosure for realizing the above-described objectives. The method may include generating an auxetic including a plurality of unit structures and adhering one or more elastic sheets to one surface of the auxetic.
Claims9
A method of manufacturing a stretchable substrate, the method comprising:
- generating a first auxetic including a plurality of first unit structures and a first fixing part, and a second auxetic including a plurality of second unit structures and a second fixing part,
- wherein each unit structure of the plurality of first unit structures and the plurality of second unit structures has a porous pattern and includes at least one hole on a sidewall of the unit structure;
- adhering one or more elastic sheets to one surface of each of the first auxetic and the second auxetic;
- and
- stacking the second auxetic on the first auxetic,
- wherein the plurality of second unit structures of the second auxetic are arranged to be offset from the plurality of first unit structures of the first auxetic, and
- wherein the first fixing part of the first auxetic and the second fixing part of the second auxetic have different formation directions and reduce contraction in a three-dimensional (3D) direction.
