Sound can levitate objects of different sizes and materials through air, water and tissue. This allows us to manipulate cells, liquids, compounds or living things without touching or contaminating ...

Like an invisible pair of tweezers, sound waves can be used to levitate tiny objects in the air. While DIY acoustic levitation kits can be found online, the technique has important applications for ...

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 ...

Acoustic streaming generated by airborne ultrasonic phased arrays plays a critical role in the performance of advanced ultrasonic technologies, including midair haptic feedback, odor delivery, and ...

Levitation techniques are no longer confined to the laboratory thanks to engineers who have developed an easier way for suspending matter in mid-air by developing a 3-D-printed acoustic levitator.

No more clumping: Sue Shi and Scott Waitukaitis in their lab at ISTA, where they developed a way to overcome "acoustic collapse" – a fundamental limitation of acoustic levitation – by adding electric ...

Researchers have developed a technique for generating acoustic bottles in open air that can bend the paths of sound waves along prescribed convex trajectories. These self-bending bottle beams hold ...

Engineers in Switzerland have successfully levitated both a particle of instant coffee and a droplet of water using high frequency sounds to make them collide. The result was a very tiny cup of coffee ...

A team of mechanical engineers from the University of Bristol has developed an easier way for suspending small matter in the air: they built an acoustic levitator with readily accessible electronics ...
