Miniaturized ultrasonic device capable of capturing and moving single cells and tiny living creatures.
University of Glasgow researchers have devised a Heptagon Acoustic Tweezer which makes use of resonance for manipulating matter. This sonic tweezer uses acoustic force to build cell matrices with the possibility of repairing injured nerves.

The geometry of the plastic sheets and placement of the holes interact with sound waves to make it (and objects beneath it) appear as if they are not there.
Duke University engineers have demonstrated the world’s first three-dimensional acoustic cloak using a few perforated sheets of plastic and extensive computation. The new device reroutes sound waves to create the impression that both the cloak and anything beneath it are not there. (Video)

Three-dimensional dancing on soundwaves.
We are nearing the middle of the second decade of the 21st century and we finally have video phones. But where are the floating skateboards and flying cars? Perhaps what researchers are describing as “acoustic levitation ballet” points to some eventual possibilities.

For decades scientists have been able to use the power of sound to levitate small items — including insects and fish. But now researchers in Switzerland have figured out how to move objects around in midair, according to a new study.

ShotSpotter will precisely and instantaneously locate shooters.
Not a single person reports the gunshots ring out in the dead of night. Yet police know exactly where the shots came from, even before they arrive on the scene.
