On page 4507, S. P. Lacour and co‐workers present highly conductive and stretchable solid–liquid films that are formed by physical vapor deposition of gallium onto an alloying gold layer. The image shows patterns defined by lift‐off on an elastomer membrane. The magnified view is a false‐color scanning electron microscopy (SEM) image (×5000) of the surface of the films under 50% applied strain, showing the liquid Ga (blue–gray) flowing between the AuGa 2 /Ga clusters (gold).
