Measuring air flow in an HVAC duct can be a tricky business. Paddle wheel and turbine flow meters introduce not only resistance but maintenance issue due to accumulated dust and debris. Being able to ...

Researchers have developed a novel wearable strain sensor based on the modulation of optical transmittance of a carbon nanotube (CNT)-embedded elastomer. The sensor is capable of sensitive, stable, ...

Strain gauge sensors measure the strain (displacement) of an object under an applied force. When they are adhesively attached to the object under stress (an applied force), they deform with the object ...

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 ...

The miniature-format strain sensors DST20 complement the Baumer portfolio by adding a compact and cost- efficient system for measuring large forces above 10,000 N even in confined spaces. With their ...
