Magnetic fields are all around us. We can’t really feel or see them ourselves, per se, but we can map them with the right ...

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 ...

The new electronic intervention called ‘Kisan Mitra Chhadi’ is intended to reduce the many lives lost to snake bites in rural India. This can be tough.

I’m already loving this device, and I haven’t even touched one. Arduino announced it has collaborated with M5Stack to develop the new compact and powerful Nesso N1 IoT development kit. This system ...

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.

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 ...
