Vargas et al. designed a collection of low-cost sensors and circuits for plasma experiments, providing easier access to ...
Optical sensors articles from across Nature Portfolio Optical sensors are a broad class of device for detecting light intensity.
When a gas absorbs infra-red rays, it is heated and its pressure increases. If the stream of radiation is interrupted at sonic frequency, there are rapid changes of pressure in the gas.
This review explores the recent progress of electrical, gravimetric, and optical sub-ppm ammonia gas sensors and their humidity tolerance at room temperature. By considering the humidity interference ...
Food safety assurance is crucial, particularly in identifying prohibited colors like brilliant blue (BB) that may pose significant health risks when used in food products. Surface plasmon resonance ...
Invisible to the untrained eye, DFOS technology turns standard fiber optic cables into long-range, high-resolution sensing ...
CeNS Scientists Develop Low-Cost Sensor to Detect Toxic Sulfur Dioxide Gas Sulfur dioxide is a toxic air pollutant released predominantly from vehicle exhaust, industrial emissions, and burning fossil ...
The nondestructive and rapid detection of Listeria monocytogenes in foodstuffs is critical for ensuring food safety, but it remains a significant challenge. Herein, we propose an efficient ...
