Abstract
Provided is a method of manufacturing a stretchable substrate according to various embodiments of the present disclosure in order to implement the above-described objects. The method may include forming an auxetic including a plurality of unit structures and forming one or more microstructures.
Claims5
A method of manufacturing a stretchable substrate, the method comprising:
- forming an auxetic on a fixing surface, wherein the auxetic comprises a plurality of unit structures and a plurality of microstructures, wherein:
- the plurality of unit structures have the same reentrant shape;
- the plurality of microstructures comprise first microstructures, which are protruded from inner surfaces of a respective unit structure of the plurality of unit structures;
- each first microstructure has a hemispherical shape;
- the plurality of microstructures comprise second microstructures;
- each second microstructure comprises a first triangle plate and a second triangle plate;
- a first vertex of the first triangle plate and a first vertex of the second triangle are facing each other at a distance;
- a second vertex and a third vertex of the first triangle are in contact with a first end surface inside the respective unit structure of the plurality of unit structures;
- and a second vertex and a third vertex of the second triangle are in contact with a second end surface inside the respective unit structure of the plurality of unit structures;
- forming a substrate part on the fixing surface;
- and
- separating the fixing surface from the plurality of microstructures and the substrate part.
