Abstract: This paper discusses the design, optimization, and applications of piezoelectric micromachined ultrasonic transducers (PMUTs) for ultrasonic sensing systems. PMUTs offer advantages such as ...

Abstract: Flexural ultrasonic transducers (FUTs) are a promising route for a new generation of adaptive ultrasonic sensors, for applications including flow and proximity sensing. One major limitation ...

Focused ultrasound with microbubbles is a noninvasive procedure that transiently opens the blood-brain barrier (BBB) using low-intensity sound waves. The openings reseal within 24 hours. Using MRI to ...

The British Army has stopped using its Ajax armored fighting vehicle after soldiers became unwell from vibrations and noise. Around 30 soldiers were affected during war games involving the NATO ...

MIT engineers have created an ultrasonic device that rapidly frees water from materials designed to absorb moisture from the air. Instead of waiting hours for heat to evaporate the trapped water, the ...

What if you could pull drinking water straight from the air in minutes, not hours? This ultrasonic system could change how water reaches dry communities. MIT engineers designed an ultrasonic system to ...

Researchers designed an ultrasonic system to “shake” water out of an atmospheric water harvester. The design (two prototypes shown in photo) can recover captured water in minutes rather than hours.

Vibration plates are everywhere right now. Brands claim they can improve circulation and bone health, enhance recovery and joint health, and provide lymphatic drainage, but when they cost anywhere ...
