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 ...

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.

Levitation may sound like magic, but there are a wide variety of physical phenomena that can be manipulated to generate the desired effect. In this case, [Mirko Pavleski] has built a rig capable of ...

A team develops an ultrasensitive broadband transparent ultrasound transducer. The 'ultrasound-photoacoustic dual-modal imaging system' combines molecular imaging contrast with ultrasound imaging, and ...

Ultrasound works by sending sound waves through the body. Doctors can recommend ultrasound therapy to treat pain. It may work best alongside other treatments. Many people know ultrasound as an imaging ...

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 ...
