A new acoustic levitation technique combines sound waves and electric charge to control multiple particles without physical ...

Levitating sensors are moving from science-fiction imagery to practical laboratory tools, promising a new generation of ...

Using sound to get objects to float works well if a single particle is levitated, but it causes multiple particles to collapse into a clump in mid-air. Physicists at the Institute of Science and ...
