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 instruments use beams of high frequency, short wave signals to inspect, monitor, and measure materials and components. Ultrasonic energy is introduced into tested materials or components ...

Acoustic emission instruments and noise detectors are NDT equipment for monitoring conditions and detecting changes in mechanical, electrical and process systems. Acoustic emission instruments are ...

A joint research team led by Professors Sangyoon Han and Jaesok Yu of the Department of Robotics and Mechatronics Engineering ...

Ultrasonic sensors have been a staple in the sensing space for several decades due to their capabilities, flexibility, and low cost. As the rise of IoT finds its way into virtually every market and ...

A chip-scale optical ultrasonic sensor detects MHz signals through air with 25,000-fold higher responsivity, enabling ...

A new ultrasonic test method can acquire high-resolution shale data in the lab by using new geometries for sample testing with specialized equipment suited for measuring shale formations at reservoir ...

Ultrasonic flow meters can be used in a variety of applications where non-intrusive measurement is an advantage. Large pipes, chemical feed pipes, steam pipes, and some gas pipes are just some ...

Aerial ultrasonic waves—high‐frequency acoustic vibrations propagating through air—have emerged as a versatile tool in a range of materials‐processing operations. By harnessing acoustic radiation ...

Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

Ultrasonics or ultrasound is a radar-like system that uses ultrasonic signals at frequencies above those typical for human hearing, usually above 16 to 20 kHz. The 40- to 70-kHz range tends to be most ...
