I believe the single most important factor is that the most accurate flowmeters have a close connection between the operating ...

A newly developed imaging method blends ultrasound and photoacoustics to capture both tissue structure and blood-vessel function in 3D.

Every heartbeat pushes pressure through your arteries, and that pressure shifts from moment to moment. Yet most people still ...

When [Electron Impressions] used a powerful ultrasonic array to project a narrow beam of sound toward a target, he described ...

Abstract: Smart rings are now commonly used for proactive health monitoring, especially for tracking cardiovascular parameters like Pulse Rate (PR), owing to their unobtrusive nature, comfortable ...

This work introduces a miniaturized ambient temperature sensor using piezoelectric micromachined ultrasound transducers (PMUTs) and indirect time-of-flight (iTOF) measurement. Leveraging ...

Jan. 17, 2026 Engineers have created a device that generates incredibly tiny, earthquake-like vibrations on a microchip—and it could transform future electronics. Using a new kind of “phonon laser,” ...
