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 ...

Monitoring trace gases with high sensitivity and selectivity is essential for environmental safety and smart monitoring systems.

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 ...

Fujitsu Laboratories today announced the world's first successful development of an exquisitely sensitive gas sensor based on a new principle that takes advantage of graphene, a material in which ...

Sensors that measure air flow, air quality, and chemical makeup are being deployed increasingly for both indoor and outdoor environmental monitoring, in homes, automobiles, and industrial facilities.

New research has shown how the quantum mechanical principle of strong coupling opens unrivalled possibilities for designing optical filters. A team of researchers from the University of Cologne, ...

Patients who remain in bed for long periods of time may develop pressure sores, which can in turn become potentially life-threatening chronic skin ulcers. A new sensor could help keep that from ...
