Ultrasonic levitation is by now a familiar trick: one or more ultrasonic transducers create a standing wave, and small objects can be held in the nodes of this standing wave. With a sufficiently large ...

A new review article unveils the world of flexible micromachined ultrasound transducers (MUTs), an emerging technology at the intersection of wearables, ultrasound, and MEMS. These cutting-edge ...

A research team has developed the world's first high-performance photoacoustic endoscopy based on a transparent ultrasonic transducer. Their findings were recently published in the journal Science ...

The notion of a phased array was initially articulated by Nobel Prize recipient K. F. Braun. Phased arrays have subsequently evolved into a formidable mechanism for wave manipulation. This assertion ...

Most ultrasonic flaw detection and thickness gaging are carried out at normal temperatures. However, sometimes a hot material requires testing, for example, in process industries. In these instances, ...
