Three‐dimensional (3D) conductive composites with remarkable flexibility, compressibility, and stretchability are fabricated by solution deposition of thin metal coatings on chemically modified, macroscopically continuous, 3D polyurethane sponges, followed by infiltration of the metallic sponges with polydimethylsiloxane (PDMS). These low‐cost conductive composites are used as high‐performance interconnects for flexible and stretchable light‐emitting diode (LED) arrays, even with severe surface abrasion or cutting.
