Stacked structures for stretchable device, stretchable devices, methods of manufacturing the same, display panels, sensors, and electronic devices

A stacked structure for a stretchable device, the stacked structure comprising:

• a stretchable layer, the stretchable layer including an elastic polymer;
• and
• a conductive layer on the stretchable layer, the conductive layer including a metal,
• wherein the stretchable layer includes a first depth region and a second depth region sequentially disposed in a depth direction from a surface of the stretchable layer that is in contact with the conductive layer,
• wherein metal atoms of the metal are penetrated or diffused into the elastic polymer in the first depth region such that the first depth region includes the metal, and
• the metal in the first depth region is in a form of metal clusters.
