We’ve all seen acoustic levitation, it’s one of the scientific novelties of our age and a regular on the circuit of really impressive physical demonstrations of science to the public. The sight of ...

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 ...

Acoustic levitators are already pretty intriguing devices, in that they use opposing sound waves to suspend small objects in mid-air. Now, however, scientists from Brazil's University of São Paulo ...

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 ...

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.

People have been able to levitate small objects using sound for years. But applications for the technique are severely limited because scientists hadn’t figured out how to control and manipulate the ...

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 ...

Precisely sculpted sound waves have been used to levitate components and tiny droplets of quick-setting glue to build complex structures piece by piece in mid-air. The approach may have practical ...

Using a technique that has possible applications in acoustic cloaking, sonic levitation, ultrasonic imaging, and particle manipulation, scientists at the University of California Berkeley claim to ...

In a sci-fi feeling first, engineers at the University of Bristol used the world’s most powerful acoustic tractor beam to demonstrate that it’s possible to stably contain objects larger than the ...

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 ...
