A dust sensor is an optical electronic system to detect fine particles such as dust. In principle, an optical dust sensor detects the dust particle concentration the in air by using an optical sensing ...

New surface-mount optical sensors increase vertical headroom, enabling more flexible encoder and position-sensing designs across industrial and consumer electronics.

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 ...

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 ...

In the pursuit of clean and renewable energy, hydrogen plays an important role. But a major challenge facing this transition is that the gas is explosive when mixed with air. For this reason, it is ...

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, ...

Understanding acoustic feedback in hearing aids. Power consumption challenges in hearing aids. Functionality integration and its impact on energy consumption. The benefits of using photoreflectors for ...
