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, ...

Ultrasound transducer technology forms a cornerstone of modern diagnostic and therapeutic systems, harnessing piezoelectric materials to convert electrical energy into acoustic waves, and vice versa.

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 ...

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 ...

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

Today, a vast number of micro-manufactured sensors, actuators and components vibrate at frequencies in the high MHz range. Some examples of these high-frequency vibrating systems include surface ...

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, ...

Infineon Technologies AG has claimed the first integrated one-chip solution for a MEMS-based ultrasonic transducer in a smaller footprint with improved performance and higher functionality. The MEMS ...

The average Hackaday reader is likely at least familiar with acoustic levitation — a technique by which carefully arranged ultrasonic transducers can be used to suspend an object in the air ...
