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.

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 ...

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 ...

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 ...

The HC-SR04 ultrasonic range sensor is a pretty cool pre-wired module that you actually enjoy using when you start playing with electronics, microcontrollers, and robotics. As you might have noticed, ...

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, ...

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 ...

Scientists develop a high-performance photoacoustic endoscopy featuring a transparent ultrasound transducer. Recently, a research team consisting of Professor Chulhong Kim from the Department of ...

When it comes to dental checkups, no one likes having their gums poked with the periodontal probe. Well, they may soon no longer have to, thanks to a gum-assessing toothbrush-shaped mini ultrasound ...
