A two-in-one technology provides 3D images of structural defects, such as those that can develop in aircraft and power plants. A new system, developed by Tohoku University researchers in Japan in ...

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 ...

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 ...

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 ...

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 ...

A new system, developed by Tohoku University researchers in Japan in collaboration with Los Alamos National Laboratory in the US, takes 3D images that can detect defects in metallic structures. The ...

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, ...
