For this, they used a sequence of frequencies at which the objects moved along the nodal lines for the calculated trajectories.
Scientists have learned to control the movement of objects using sound.
Due to the high accuracy method, the researchers managed to even write the words, by controlling the objects through sound.
Experts used a sequence of frequencies, which made things move along nodal lines for particular trajectories. As reported by Chuan Zhou, author of the research paper, scientists managed to establish the record for the number of independent movements, which can be synchronously controlled by one source.
The scientific method proposed by Finnish researchers, may find application in a variety of places to move floating objects in the sorting process of microelectronics. In addition, the technology can be used in the pharmaceutical industry.
