Ultrasonic phased arrays are one of the wonders of the moment, with videos of small items being levitated by them shared far and wide. We’ve all seen them and some of us have even wondered about ...

Ultrasonic transducers are incredible, with them you can detect distances, as well as levitate and peer through objects. They can emit and receive ultrasonic soundwaves (typically above 18khz) and ...

Remote ultrasonic arrays made of visible and invisible laser radiation are used to provide ultrasonic images of the interior of solids such a metal parts. Adaptive Laser Induced Phased Arrays are ...

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

A device that can perform 3D ultrasound imaging with just one large piezoelectric ultrasound transmitter and receiver has been developed by researchers in the Netherlands. Most ultrasound imagers use ...
