Midair haptics and levitation may get steadier with predictable ultrasonic airflow
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 ...
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 ...
What does the future of construction look like? Autonomous machines buzzing around a building site? Giant 3D printers extruding walls and floors? Looking forward even farther, researchers at the ...
A study on the levitation technique titled "High-speed acoustic holography with arbitrary scattering objects" has been published in the journal Science Advances. Researchers from the University ...
