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 ...

Although basic analog ultrasound imaging began about 50 years ago, today’s machines are largely digital and provide many more options as well as images with much greater detail and color. Most modern ...

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 ...

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 ...
