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 ...

A new light-based sensor can spot incredibly tiny amounts of cancer biomarkers in blood, raising the possibility of earlier ...

A new prototype sensor is capable of detecting errors in MRI scans using laser light and gas. The new sensor can thereby do what is impossible for current electrical sensors -- and hopefully pave the ...

Scientists have developed a new kind of wearable sensor that can detect signs of eye disease—without drawing blood or using expensive lab equipment. Instead, it’s a soft, non-invasive patch placed ...

I want to add an analog ambient light detector to one of my electronics projects. To do that, I picked the TEMT6000 ambient light sensor. TEMT6000 is a silicon NPN epitaxial planar phototransistor in ...

A portable detector the size of a cookie box reveals in real time the cosmic particles that pass through your body every ...
