Ultrasonics or ultrasound is a radar-like system that uses ultrasonic signals at frequencies above those typical for human hearing, usually above 16 to 20 kHz. The 40- to 70-kHz range tends to be most ...

Auburn, MA – PI, a global leader in piezoelectric materials, piezo actuators and transducers, extends its selection of high quality piezoceramic elements. Available in various sizes and geometries, ...

Piezoelectric micromachined ultrasonic transducers (PMUTs) harness the direct and inverse piezoelectric effects in thin-film materials deposited on micromachined silicon substrates to generate and ...

Before humans discovered ultrasound for a variety of medical, technical and military applications, nature had perfected it over millions of years for navigation under and above water. Dolphins and ...

Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

The 'ultrasound-photoacoustic dual-modal imaging system' combines molecular imaging contrast with ultrasound imaging, and it can visualize molecular and structural information inside the body in real ...

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 ...

In a recently published study in the journal EPSL neuroelectronics, researchers from The Pennsylvania State University and Washington University in St. Louis have introduced a modular 16-channel ...

Why new and disruptive medical applications are best driven by ultrasonic transducers. Piezoelectric transducers generate HIFU, high-intensity focused ultrasound, enabling contactless treatment and ...

Ultrasonic nondestructive testing, also known as ultrasonic NDT or simply UT, is a method of characterizing the thickness or internal structure of a test piece using high-frequency sound waves. The ...

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, ...
