Real-time ultrafast humidity sensing optical sensor

The Hercules beetle native to South America has a fascinating trait of changing its shell colors depending on the external humidity conditions. This is because the inside of the beetle's shell consists of porous lattice structure ...

Camels' noses inspire a new humidity sensor

Camels have a renowned ability to survive on little water. They are also adept at finding something to drink in the vast desert, using noses that are exquisite moisture detectors. In a new study in ACS Nano, researchers describe ...

New sensor detects low air humidity

Measuring air humidity is important in many areas. However, conventional sensors in hygrometers have so far not been able to determine a very low water vapor content. Physicists at the University of Duisburg-Essen (UDE) and ...

Plant health management by flexible electronics

The emergence of biotic and abiotic stresses poses potential impairment on plant growth and yield. Accurate monitoring and assessment of plant health status is therefore highly important; however, conventional bulky and heavy ...

Smart windows that self-illuminate on rainy days

Smart windows that automatically change colors depending on the intensity of sunlight are gaining attention as they can reduce energy bills by blocking the sun's visible rays during summer. But what about windows that change ...

Researchers develop a black phosphorus all-fiber humidity sensor

A research group led by Prof. LI Jia and Prof. XU Xuefeng from the Shenzhen Institutes of Advanced Technology (SIAT) of the Chinese Academy of Sciences, along with Prof. YANG Dexing from Northwestern Polytechnical University, ...

From rain to flood

Extreme weather events such as thunderstorms, heavy rainfall and resulting floods, influence Earth and environmental systems in the long term. To study the impacts of hydrological extremes holistically—from precipitation ...

New cellulose-based material represents three sensors in one

Cellulose soaked in a carefully designed polymer mixture acts as a sensor to measure pressure, temperature and humidity at the same time. The measurements are completely independent of each other. The ability to measure pressure, ...
