In the medical applications of ultrasonic imaging, sound waves of high frequency are usually employed to produce in-depth cross-sectional images of internal organs. Special multi-element transducers ...

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 ...

Austenitic welds and welds that contain heterogenous weld materials are increasingly used in various industries. These welds can be used to manufacture components with enhanced or custom-engineered ...

Holodeck, anyone? Researchers at Bristol University are developing a system known as UltraHaptics that uses ultrasonic force fields to project the tactile sensations of objects in midair. Currently ...

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 ...

1. Ultrahaptics uses a phased array of ultrasonic speakers fired at precisely selected intervals so the intersection of the waves hit the hand providing a tiny forceful vibration. Ultrahaptics hasn’t ...

Detecting objects underwater isn’t an easy challenge, especially when things get murky and dark. Radio waves don’t propagate well, so most techniques rely on sound. Sonar is itself farily simple, ...

The inaugural Data Center POWER eXchange brought the data center power ecosystem together in Denver for a focused, one-day summit on the infrastructure shaping the future of digital growth. From site ...
