Abstract
A stretchable substrate includes a first elastomer, a plurality of unit devices on the stretchable substrate, a connecting wire configured to electrically connect adjacent unit devices, and a plurality of auxiliary structures each including a second elastomer and each at least partially overlapping with at least one unit device or the connecting wire, wherein the first elastomer and the second elastomer are separate, respective polymers that commonly include at least one structural unit.
Claims28
A stretchable device, comprising:
- a stretchable substrate including a first elastomer;
- a plurality of unit devices on the stretchable substrate;
- a connecting wire configured to electrically connect adjacent unit devices of the plurality of unit devices;
- and
- a plurality of auxiliary structures, each auxiliary structure of the plurality of auxiliary structures at least partially overlapping with at least one unit device of the plurality of unit devices and/or the connecting wire in a vertical direction that is perpendicular to an upper surface of the stretchable substrate, the plurality of auxiliary structures each including a second elastomer,
- wherein the first elastomer and the second elastomer are separate, respective polymers that commonly include at least one structural unit.
