Advances in ultrasound—the same imaging technology that uses sound waves to allow doctors to monitor babies in utero—are being applied by engineers at the University of California San Diego to make ...

Existing defect detection tools using ultrasound rely on phased array ultrasound. In this method, many transducers are pointed in the same direction to generate an image of that specific area. This ...

There have been important technological advancements made in the nondestructive testing (NDT) industry with total focusing method (TFM) capable inspection devices becoming more common. In terms of ...

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 ...

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 ...

Who wouldn’t want an autonomous drone to deliver cans of fizzy drink fresh from the fridge? [Alex Toussaint] did, and in thinking how such a machine might work he embarked on a path that eventually ...

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 ...

Researchers at the University of California San Diego have created a coin-sized flexible stick-on ultrasonic phased-array that allows blood pressure to be measured in arteries below surface layers.

Three-dimensional printed acoustic lenses that focus ultrasound beams to arbitrary shapes within the brain have been developed by researchers at the Technical University of Valencia. The lenses ...
