Researchers at the Georgia Institute of Technology have created a passive motion/contact sensor that detects motion using only sound. Without electricity, electronics, or batteries. The sensors are ...

Dr. Park Chan Wook (Postdoctoral Researcher, Non-Destructive Metrology Group, KRISS); The Korea Research Institute of Standards and Science (KRISS, President Lee Ho-seong) has developed an ultrasonic ...

A new technology has been developed that enables cuffless non-invasive blood pressure monitoring by using ultrasonic to track real-time changes in vascular diameter—without the need for a traditional ...

I tried a techy new knife at CES 2026. Here's my take on whether this pricey blade is worthy of the hype. David lives in Brooklyn where he's spent more than a decade covering all things edible, ...

You brush your teeth, floss regularly and faithfully wear your retainer every night. But despite your diligent oral health habits, your retainer or mouth guard can get yellowed, cloudy or stained.

Small-group instruction has been a popular component of K-3 literacy education for many years. However, there are inevitable trade-offs. Too much reliance on small-group instruction means that ...

MIT researchers have found a way to use the mechanical vibrations of sound waves to shake water molecules free from a storage medium. The breakthrough significantly speeds up the process of harvesting ...

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 ...

A new category of sensing technology transforms mobile robot vision from 2D to 3D, improves safety performance and provides 50-80% cost savings compared to traditional, LiDAR-based systems and sensor ...
