Wristbands do a health check while you work out

Next-generation fitness sensors could give deeper insights into human health through noninvasive testing of bodily fluids. A stretchy patch developed at KAUST could help this approach by making it easier to analyze sweat ...

A hydrogen sensor that works at room temperature

Researchers at TU Delft have developed a highly sensitive and versatile hydrogen sensor that works at room temperature. The sensor is made of a thin layer of a material called tungsten trioxide.

Sensor detects whiff of bad breath

Ever wish you could do a quick "breath check" before an important meeting or a big date? Now researchers, reporting in ACS' journal Analytical Chemistry, have developed a sensor that detects tiny amounts of hydrogen sulfide ...

Chemists improve hydrogen sensors

A group of scientists from the Siberian Federal University (SFU, Krasnoyarsk, Russia) and the Nikolaev Institute of Inorganic Chemistry (NIIC, Novosibirsk, Russia) have combined the useful properties of metal phthalocyanines ...

Scientists build hydrogen sensor readable with the naked eye

According to many scientists, the proposed hydrogen economy, positioning hydrogen as the most important carrier of sustainably generated energy, is an inevitable development. Unfortunately, the use of hydrogen entails certain ...

Researchers greenlight gas detection at room temperature

Russian researchers have developed a mechanism for detecting molecular hydrogen using green light to illuminate a nanocrystalline composite sensor based on zinc and indium oxides. This enables a gas sensor operating at room ...
