Acoustic Levitator Can Move Objects in Mid-Air

Jan-09-15 Researchers in Brazil have created a non-resonant acoustic levitator that could find its way into practical use.

Typical acoustic levitators must be aligned precisely in order for the sound waves to resonate properly and support the standing wave. However, the acoustic levitator from the Brazilian team is designed to function as a non-resonant acoustic levitator, which means its components can be rearranged even while suspending an object. The suspended object can also be moved in mid-air by altering the orientation of the system's reflector.

The team hopes to develop the device to the point where it can levitate larger objects, perhaps leading to applications in pharmaceuticals and manufacturing.
