Scientists Use Sound Waves To Levitate, Move Objects

Posted by samzenpus on from the they-like-to-move-it-move-it dept.

sciencehabit writes "The tragic opera Rigoletto may move you to tears, but here's a more literal application of the moving power of sound. Sound waves with frequencies just above human hearing can levitate tiny particles and liquid droplets and even move them around, a team of engineers has demonstrated. The advance could open up new ways to handle delicate materials or mix pharmaceuticals."

    Just for the record all Opera moves me tears, what the fuck is up with the middle school rhetorical flourish?

    Also this is basically decades old. How much is /. getting for the clicks?

    Because resonances can often get you more bang for your energy buck than direct impulse.

    That, and they want to move things carefully and precisely. This seems like it would be a lot more stable than using air flows.
