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 ...

A new technology has been developed that enables cuffless noninvasive blood pressure monitoring by using ultrasonic to track real-time changes in vascular diameter—without the need for a traditional ...

New ultrasound-based wearable measures blood pressure from deep vessels without a cuff, improving accuracy and comfort.

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 ...

Researchers from the California Institute of Technology (Caltech) and the University of Southern California (USC) have developed a hybrid imaging system that provides three-dimensional, colour-coded ...

Ultrasonic nondestructive testing, also known as ultrasonic NDT or simply UT, is a method of characterizing the thickness or internal structure of a test piece using high-frequency sound waves. The ...

Ultrasonic phased arrays are one of the wonders of the moment, with videos of small items being levitated by them shared far and wide. We’ve all seen them and some of us have even wondered about ...

Imagine a device that’s the size of a bandaid, costs under $100, and can see inside the human body. Pretty impressive, considering current similar technology is often bulky and expensive. Now, ...
