Many types of sensor now use graphene as the response material and has become a hot area of graphene research. Despite not being the most obvious use of graphene to outsiders, it is an area in which a lot of research is being undertaken and commercialized.
A new addition to the graphene sensor family has now made its presence known in the academic world because a team of Researchers from South Korea have created a graphene nanoribbon sensor which can measure high vacuum pressures.
There are many sensors nowadays coming out of academia which use graphene, at least in part, to detect an environmental or invoked response. Many sensors have gained interest from industry, and as a result, new graphene-based sensors are appearing all of the time. To date, the most common sensors using graphene are humidity, temperature, gas and pressure sensors.
The area of graphene pressure sensors is a growing area within itself and already consists of MEMS piezoresistive pressure sensors, field emission pressure sensors and squeeze-film pressure sensors, to name a few.
The area of graphene pressure sensors has exploded in recent years and has been brought on by the high flexibility exhibited by graphene and the easily measurable response from the sheet to the detector.
