Tsukuba, Japan—Airborne ultrasonic phased arrays focus ultrasonic waves at prescribed locations in space and dynamically steer them, enabling applications such as noncontact tactile feedback, odor ...

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 ...

Time crystals, a collection of particles that "tick"—or move back and forth in repeating cycles—were first theorized and then discovered about a decade ago. While scientists have yet to create ...

Long range acoustic devices (LRADs) are often referred to as sound cannons and have been used against protesters in the US with damaging impacts, with some saying they should be considered weapons.

Abstract: The use of no-insulation coils in high-temperature superconductor levitation bearings has the potential to produce bulk-like characteristics without the associated size, quality and ...

This repository provides all the necessary resources, including code, schematics, and documentation, to build and experiment with your very own acoustic levitation system. Our repository is dedicated ...
