The average Hackaday reader is likely at least familiar with acoustic levitation — a technique by which carefully arranged ultrasonic transducers can be used to suspend an object in the air ...

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 ...

For those that haven’t heard, ultrasonic levitation is a process by which two or more ultrasonic transducers are set opposite to each other and excited in such a way as to create a standing wave ...

Acoustic levitation conjures images of Star Trek­-style tractor beams and ultrasonic hover boards, but in reality floating objects on a cushion of sound occurs on far smaller scales. That’s in part ...

A robot arm that can pick up and carry objects without touching them using ultrasonic levitation is being developed by scientists. Researchers at ETH Zurich used an array of tiny speakers that emit ...

Levitation is no longer just the realm of magicians, with engineers dabbling in ways to suspend objects in midair using magnets, heat flow or sound waves. Unfortunately, it usually only works with ...

Scientists have long dreamed of using acoustic levitation to float objects, but there has been one big catch: you couldn't lift an object larger than the wavelength without being picky about what ...

Using ultrasound, a team of Japanese scientists has levitated small particles, and moved them around mid-air. It’s incredible to see. This isn’t the first time we’ve seen ultrasonic levitation, but it ...

Researchers in Tokyo have put a new twist on the use of sound to suspend objects in air. They've used ultrasonic standing waves to trap pieces of wood, metal, and water – and even move them around.

Levitation isn't just for mystics anymore. A Japanese technology team has demonstrated ultrasonic levitation of objects that for the first time works in three dimensions. This means that as opposed to ...
