Dances with waves: Breakthrough in moving small objects using acoustics

Researchers have made a breakthrough in controlling the motion of multiple objects on a vibrating plate with a single acoustic source. By playing carefully constructed melodies, the scientists can simultaneously and independently move multiple objects on the plate towards desired targets. This has enabled scientists, for instance, writing words consisting of separate letters with loose metal pieces on the plate by playing a melody.
