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 ...

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 ...

Piezoelectric ultrasonic transducers play a critical role in modern sensing and actuation by converting electrical signals into high‐frequency mechanical vibrations and vice versa. Recent advances ...

To increase the accessibility of piezoelectric transducers and actuators for OEM designers, manufacturers may package these devices inside a protective arrangement of flexures. This approach offers a ...

Any instrument to survive the trip to and operating conditions on Mars needs to be designed to withstand the most adversary conditions. NASA’s Rover Curiosity has been analyzing mineral probes on the ...

The increasing miniaturization and sophistication of electronic products, ranging from consumer media devices to medical diagnostic tools to defense-related sonar applications, presents a bounty of ...

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 ...

A 1-op-amp circuit for processing the signal from a piezoelectric accelerometer. Accelerometers are used in instrumentation applications to measure a change in velocity with respect to time or an ...

The P-878 DuraAct Power piezo patch transducer from PI Ceramic uses an operating voltage of only -20 to 120V compared to the high driving voltages of 250 to 1000V typically used with alternative ...
