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 ...

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 ...

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 ...

In an era where industrial automation discussions are often dominated by advanced sensing technologies and digital transformation initiatives, continuous ultrasonic level measurement continues to hold ...

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 ...

Ultrasonic flow measurement exploits sound waves to determine the velocity and volume of fluids in pipes and open channels. The most common approach, the transit-time method, measures the difference ...

An evaluation kit from TDK showcases its USSM1.0 PLUS-FS ultrasonic sensor module for designs requiring obstacle detection and distance measurement. The sensor operates in harsh industrial ...

Both magnetic flux leakage (MFL) and ultrasonic technology (UT) techniques have been used by the pipeline inline inspection (ILI) industry for decades. MFL tools remain the workhorse for metal loss ...

Sonair is pushing towards a new sensor built on 3D ultrasonic technology, giving autonomous robotics the power to see and make the right decisions. Ralph W. Bernstein is the senior business developer ...

RESONIKS, an acoustic testing startup based in The Hague, has introduced the MPK801, a digital measurement microphone combining a stated 20Hz–80kHz frequency range with Ethernet connectivity and ...
