Chemical sensors, of varying composition, are used across a wide range of industries to detect changes within a physical environment. Of the various compositions, graphene sensors have surged of late, and in many areas- biosensors, pressure sensors, gas and humidity sensors, to name a few.
Now, an international effort, composed of Researchers from Saudi Arabia, China and the US, have developed a graphene-bacterial cellulose nanofiber (GC/BCN) hybrid sensor to detect alcohol (ethanol) with great efficiency.
The demand for sensors has exponentially increased in recent years are now employed in the automobile, aerospace, safety, indoor air quality, environmental control, food, industrial production and medical sectors. Despite sensor research being established, there is still a demand for new and improved sensors across the varying industries.
Graphene sensors are always being developed, with new devices coming out that sense a different type of molecule. Even though the applications of graphene sensors are widespread, they all come back to one central application- flexible electronics, which is often (but not always) the device type that graphene sensors adopt, independent of the application.
