Note: In addition, there are many nano sensor technologies that  require the use of external stimulation and measurement to work.  Wireless communication between nano sensors and micro and macro equipment can  meet this need. 

Regarding nano sensors, their measurement performance requires that they  be placed inside the environment from which they must measure parameters, and  the area covered by a nano sensor  is limited to its surrounding environment. Meanwhile, a network of nano sensors can  cover a wider area and perform  more network processing  . The molecular method is to send and receive coded information in molecules  , while the electromagnetic communication is to send and receive  electromagnetic radiation from various nano devices.  Among these methods, the molecular method and the electromagnetic method are among the wireless methods  .


In the electromagnetic communication method, the electromagnetic communication between nano  sensors is dependent on the development and construction of two important parts, the nano antenna and  its corresponding transceiver  in the nano scale, graphene-based antennas  are used to transmit EM waves. . Graphene is a very thin monoatomic sheet  of confined carbon atoms placed on a crystal lattice  . Due to the very small dimensions of nano sensors, nano antennas  need to have a very high working frequency to be usable. However, the use of  graphene helps to solve this problem to a great extent.

 


Nanotechnology includes devices and tools  , one of whose dimensions is about one to several hundred nanometers. Based on this  , if the antennas used in the nano parts  are to be within this range, it should be expected that the electromagnetic waves used in  the communication of these systems and devices will be around several tens of terahertz, which  will include the wavelengths of the infrared, visible and ultraviolet regions. became

Conclusion : 

In addition, there are many nanosensor technologies that  require the use of external stimulation and measurement to work.  Wireless communication between nanosensors and micro and macro equipment can  meet this need.
