Highly conductive and elastic nanomembrane for skin electronics: A float assembly method enables the fabrication of highly conductive, stretchable, and ultrathin nanomembranes

Skin electronics require stretchable conductors that satisfy metal-like conductivity, high stretchability, ultrathin thickness, and ease of patternability, but it is challenging to achieve these characteristics simultaneously. The researchers developed a new float assembly method to fabricate a nanomembrane that satisfies all these requirements simultaneously. The exceptional material properties are attributed to its unique cross-sectional structure in which a monolayer of compactly assembled nanomaterials is partially embedded in an ultrathin elastomer membrane.
