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, ...

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 ...

Although ultrasonic sensors have been around for several decades, their popularity in sensing applications continues due to their capability, flexibility and relatively low cost. Products like ...

There is a lot of buzz about electromagnetic (EM) detection and ranging sensor technology, which encompass radar, lidar, infrared (IR), ultra-wide bandwidth (UWB), and many others. However, there are ...

Throughout the surgical process, the surgeon must have access to a real-time assessment of blood vessels to make evaluations relative to the flow of blood. Piezo transducers are at the heart of ...

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, ...

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 ...
