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 ...

In industrial markets, semiconductor chipsets play a huge role in the transformation of mechanical equipment to electromechanical or purely-electronic equipment. Every market segment is broken down ...

Before humans discovered ultrasound for a variety of medical, technical and military applications, nature had perfected it over millions of years for navigation under and above water. Dolphins and ...

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 ...

Ultrasound refers to any audio signal above the range of human hearing. Generally that’s accepted as 20 kHz and up. Unlike electromagnetic signals, ultrasonics are still operating in a medium – ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...

A Lithuanian company called Neurotechnology has developed a device they are calling an ultrasonic 3D printer. Built by the firm's Ultrasound Research Group, it is just a prototype at this stage and is ...

Most ultrasonic flaw detection and thickness gaging are carried out at normal temperatures. However, sometimes a hot material requires testing, for example, in process industries. In these instances, ...
