(Nanowerk News) Researchers have developed the first fully-integrated, non-dispersive infrared (NDIR) gas sensor enabled by specially engineered synthetic materials known as metamaterials. The sensor ...

Air bubble sensors are used to detect air or gas bubbles in flexible clear plastic tubes. They are intended to prevent air infusions. The air bubble sensor has no contact with the liquid and is ...

There is a growing demand for portable gas sensors, from both environmental and health sciences as well as industry. Resonant optical sensors, in particular planar micro-resonators, combine high ...

At some time or another, we’ve all had an idea we thought was so clever that we jumped on the Internet to see if somebody else had already come up with it. Most of the time, they have. But on the off ...

Although we're constantly surrounded by it, the air around us often holds plenty of substances to which we're completely oblivious. And while information about the air around us can be critical for ...

Sensors help microprocessor-based systems find their bearings. Where would embedded systems be without them? Sensors provide the windows through which microprocessor-based systems can observe their ...

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