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 ...

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 ...

Most touchscreen panels have a limited type of haptic feedback or none at all. This is also true for many types of handheld or wearable devices like watches, touchpads, keyboards, a mouse, etc. 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 ...

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 ...

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 ...

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 ...

This unique dual harvesting arrangement, which simultaneously harvests energy from magnetic fields and ultrasound sources, can provide more power than either one alone—at no cost. Why dual-source ...

Flexible piezoelectric sensors are essential to monitor the motions of both humans and humanoid robots. However, existing designs are either are costly or have limited sensitivity. In a recent study, ...

Piezoresistive (diaphragm-based) differential pressure sensors based on silicon comprise a thin silicon diaphragm in which resistors (connected together in a Wheatstone bridge) are lodged. If there is ...
