Investigating The Structure and internal Construction of Flexible Electronic Nanodevices Such as The Nanographene Gas Sensor

Note: Nano graphene gas nanosensors The unique optical and nanoelectronic properties of these nanostructures have led to the use of these nanomaterials for the development of small devices, such as low-power sensors. Graphene nanomaterials threaten other nanomaterials from the point of view of use in gas sensing.

Gas sensing with (nanomaterials) Stable, sensitive and simple electronic sensors that can detect very small amounts of gases, such sensors can be used to detect biological substances or hazardous chemical agents, among all nanomaterials, carbon nanomaterials (graphene)  are a very suitable option for this task. Carbon nanomaterials, due to their inherent properties, have a high potential for the production of automated sensors, low dimensions, and large area. Carbon structures have a high surface area, which is very ideal for sensing. Unlike polycrystalline materials such as silicon, they lack grain boundaries  , which makes the sensor stable for a long time. Some carbon materials, such as carbon nanotubes and graphene, have a high-quality crystalline nanolattice, so charge carriers in these structures move at high speeds while generating little noise. Since these two factors play a very important role in creating conductive properties, it is easier to control and multidimensional and high-quality crystalline structure.

The electromagnetic properties of carbon nanotubes (graphene) have allowed these materials to be   used in flexible electronic devices such as the Nano graphene sensor. The low energy consumption of carbon nanotube-based devices  has allowed these devices to  operate  independently and without the need for an external charging agent  . The movement of electronic signals in a chemical environment has advantages over optical methods  . In the manufacture of sensors,  graphene, as one  of the new allotropes of carbon, is overtaking  carbon nanotubes in the manufacture of sensors  . But carbon nanomaterials  are not limited to graphene and nanotubes.

Conclusion :

One of the most important reasons for the interest in making sensors  from carbon nanomaterials (graphene) is that this group of materials,  in addition to having a regular nanoscale tubular structure,  also has considerable stability; therefore,   they are very stable even when not functionalized  . Although there is a wide range of nanomaterials   . Nano graphene gas nanosensors The unique optical and nanoelectronic properties of these nanostructures have led to the use of these nanomaterials for the development of small devices, such as low-power sensors. Graphene nanomaterials threaten other nanomaterials from the point of view of use in gas sensing.
