A Network of Nanosensors Can Cover a Wider Area and Perform More Network Processing

Note: In addition, there are several nanosensor technologies that  require the use of external excitation and measurement to work.  Wireless communication between nanosensors and micro- and macro-devices can  meet this need.

In the case of nanosensors, their measurement function requires them  to be placed inside an environment of which they must measure parameters, and  the area covered by a nanosensor  is limited to its surroundings. However, a network of nanosensors can  cover a wider area and perform  more network processing  . Molecular communication is the sending and receiving of information encoded in molecules  , while electromagnetic communication is the sending and receiving  of electromagnetic radiation from various nanodevices  . Of these methods, molecular communication and electromagnetic communication  are wireless methods.  In the electromagnetic communication method, electromagnetic communication between nanosensors  depends on the development and construction of two important parts, the nanoantenna and  its corresponding transceiver  . At nanoscale, graphene-based antennas  are used to transmit EM waves. Graphene is a very thin single-atom sheet  of confined carbon atoms arranged on a crystal lattice  . Due to the very small dimensions of nanosensors, nanoantennas  require very high operating frequencies to be usable. However, the use of  graphene helps to solve this problem to a large extent.

Nanotechnology includes devices and instruments  with one of their dimensions ranging from one to several hundred nanometers. Accordingly,  if the antennas used in nano components are to  be within this range, it should be expected that the electromagnetic waves used in  the communications of these systems and devices will be around several tens of terahertz, which  will include wavelengths in the infrared, visible, and ultraviolet regions.

Conclusion :

In addition, there are several nanosensor technologies that  require the use of external excitation and measurement to operate.  Wireless communication between nanosensors and micro- and macro-devices can  fulfill this need.
