Acoustic active surfaces are developed by Peer Fischer and co‐workers based on two‐dimensional arrays of acoustically resonant micro‐bubbles, which provide highly directional propulsive forces in fluids through acoustic streaming in article number 1700933 . The surfaces are remotely powered by an external acoustic field and are directly attached to miniaturized robots to propel them with multiple degrees of freedom. Image by Alejandro Posada/MPI‐IS.
