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 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 ...

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 ...

Nondestructive testing (NDT) refers to the inspection of materials to ensure their integrity and serviceability without damaging the components in the process. There are various NDT methods used by ...

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 ...

Supplementary Table S4 shows a summary of stimulus modalities, including kHzMHz ultrasound, optogenetic optical stimulation, and electrical stimulation. Each section includes relevant recent work in ...

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, ...
