Scientists have used networks of spherical nanoparticles to create stretchable conductors in a development which could usher in a new era of elastic electrical materials.

According to a team of engineering researchers from the University of Michigan, the embedding of spherical nanoparticles in polyurethane permits the creation of materials which are bendable and flexible yet possess the conductive properties of metals. “Essentially the new nanoparticle materials behave as elastic metals,” said Nicholas Kotov, the Joseph…
