In the meantime, smart sensors with on-board processing and communication capabilities are now widely used across the internet of things (IoT). Software-based virtual sensors gene ...

Three cheap hygroscopic salt solutions on carbon nanotube sensors distinguish nine toxic gases, including warfare agents, without engineered receptor molecules.

Wherever hydrogen is present, safety sensors are required to detect leaks and prevent the formation of flammable oxyhydrogen gas when hydrogen is mixed with air. It is therefore a challenge that today ...
