You might think traffic light systems are fairly basic. After all, electric traffic signals first appeared all the way back in 1914. However, they have advanced significantly since their inception, ...

CU Boulder researchers have built high performing optical microresonators opening the door for new sensor technologies. At its simplest form, a microresonator is a tiny device that can trap light and ...

Smartphone cameras are becoming smaller, yet photos are becoming sharper. Korean researchers have elevated the limits of next-generation smartphone cameras by developing a new image sensor technology ...

Most modern cars have tire pressure monitoring systems (TPMS), which will alert you if your tires need air. While most of the readings they give are accurate, they can still fail like any other part ...

Researchers have developed a highly sensitive light-based sensor that can detect extremely low concentrations of cancer biomarkers in the blood. The new technology could one day make it possible to ...

Here's why camera sensor size beats megapixels for low light photography. Compare 1-inch sensors vs 200MP smartphones, full-frame vs APS-C image quality. Pixabay, fotografyarte The photography world ...

Photoplethysmography (PPG) is an optical sensing technique that measures blood volume changes and underpins devices ranging from hospital-grade pulse oximeters to consumer wearables that track heart ...

Modern traffic light technology isn't just a simple sequence of red, yellow, and green. It's a complex detection system designed to manage traffic flow based on real-time demand. The very first "smart ...

The $50 sensor runs on two coin cell batteries so you don’t need a nearby power source for installation. The $50 sensor runs on two coin cell batteries so you don’t need a nearby power source for ...

Presence/motion sensors are one of the best ways to make automations feel more natural, but most of them run on batteries and eventually have to be swapped. That’s one of the main reasons I really ...
