In article number 1800468 , Stefano Danzi and co‐workers introduce a new concept for on‐demand healing of metal film that does not rely on external annealing. Using exothermic Ni/Al multilayers as latent on‐chip heat sources, healing of copper and gold thin films within a few microseconds is demonstrated. The process harvests the heat carried by a self‐sustained solitary heat wave.
