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 ...

Motion and positioning devices play an integral role in the life-science and medical engineering fields, fulfilling their many different requirements. The spectrum extends from simple low-energy drive ...

Piezo sensors that can continuously monitor components as hot as 900°C have been realised by researchers at the Fraunhofer Institute for Silicate Research ISC. "We have already implemented our sensors ...

Like all ceramics, piezo ceramics are brittle materials that are well suited to handling compressive loads but are highly sensitive to bending, shear and tensile loads. A number of mechanical ...

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