Existing defect detection tools using ultrasound rely on phased array ultrasound. In this method, many transducers are pointed in the same direction to generate an image of that specific area. This ...

Researchers at the Department of Energy's Oak Ridge National Laboratory are helping to pave a path for the eventual discovery of dark matter. With new approaches to measurement in the quantum realm, ...

Abstract: The paper presents a system based on an ultrasonic emitter and two ultrasonic receivers which can locate more precise an object located in their detection range, being able to measure the ...

Quantum sensors are transforming how we measure and navigate, offering levels of precision far beyond classical systems. By exploiting atomic superposition, cold atom interferometers, and diamond NV ...

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 ...

Most planets spend their lives orbiting a star, but some are destined for exile. According to a study published in Science on Jan. 1, 2026, astronomers have successfully measured the mass and distance ...

We live in a galaxy of data. From satellites and smartwatches to social media and swipes at a register, we have ways to measure the economy to an extent that would have seemed like science fiction ...

Have you ever wondered how a robot navigates a cluttered room or how a drone maintains its altitude with pinpoint accuracy? The secret lies in the tools used to measure distance, an often-overlooked ...

We may receive a commission on purchases made from links. Though the meaning of smart home varies depending on who you ask, with so many useful smart sensors for your home, if your home isn't smart, ...

Researchers at the Harvard School of Engineering and Applied Sciences have developed a wearable sensor system capable of estimating braking and propulsion forces while running outdoors — a ...

Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...
