A newly published patent proposes a single-sided ultrasonic levitation printer that maintains contactless deposition even ...

Ultrasonic levitation — the practice of creating a standing wave between two ultrasonic sources and positioning lightweight objects such that they can float in the pressure minimums between them — has ...

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 ...

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 ...

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 ...

In laboratories from Brazil to Munich, researchers are learning to grab matter with sound alone, sculpting ultrasonic waves ...

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 ...

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.
