Configuration Enables RFID Tags to Work as Sensors
The detection and localization of gas releases, such as methane from leaking natural gas pipelines or nitrogen oxides from failing electrical equipment, require high sensitivity to the target gas and insensitivity to non-target gases. Infrared (IR) absorption spectroscopy gives highly specific...
Briefs: Photonics/Optics
When hit with light, semiconductors (materials that have an electrical resistance in between that of metals and insulators) generate an electric current....
INSIDER: Imaging
In the future, your car windshield could become a giant camera sensing objects on the road. Or each window in a home could be turned into a security camera.

Faster Photons Could Make Data Totally Secure
Transferring data using light passed along fiber optic cables has become increasingly common over the past decades, but each pulse currently contains millions of photons. That means that in principle, a portion of these could be intercepted without detection. Secure data is already encrypted, but if an...
Briefs: Photonics/Optics
The challenge of miniaturizing devices and systems is also achieving a broader dynamic range of detection for small signals such as sound, vibration, and radio waves.

Antiferromagnetic-Based Memory Processes Data at Terahertz Speeds
Data travels down fiber-optic cables at frequencies of several terahertz. As soon as the data arrives on a PC or television, this speed must be throttled down to match the data processing speed of the device components; this speed currently is in the range of a few hundred gigahertz...
