Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to ...

Biosensors are helping people with chronic conditions worldwide live better lives. However, their measurement accuracy has often been relatively low, limiting the range of possible applications.

A multilayered semiconductor acting as an optical sensor opens the way to miniaturized, adjunct spectrometers.

Researchers found that cold is detected differently in the skin than in internal organs. This split system helps explain why ...

Effective training helps workers understand gas hazards, respond to alarms, and reduce exposure to toxic, flammable, and oxygen-deficient atmospheres.

Patients are being warned to stop using some glucose monitors made by Abbott Diabetes Care after the company found malfunctioning sensors may be linked to hundreds of adverse events and several deaths ...

The study reveals strain-tunable gas sensing in Ag- and Au-doped SnSe2 monolayers, highlighting their potential for ...

Oxygen is the second most abundant element in Earth's atmosphere. Although critical for aerobic respiration, it also poses significant dangers to life. The reduction of molecular oxygen to water by ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

A pulse oximeter measures blood oxygen levels at home and in healthcare settings. Abnormally low readings on a pulse oximeter might require medical care, especially if they are below 92%. Skin color ...
