Note: Data transfer between nano-sensors can increase the capabilities and applications of nano-devices compared to their single operating mode in both complexity and range of performance. This complex and flawless process with a wide coverage range can be called Nano (Data_Telecommunication) or Nano_Telecommunication.
In the case of nanosensors, their measurement performance requires them to be located in an environment from which parameters must be measured, 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 . 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 equipment can meet this need. There are four major strategies for communicating between nanostructures :
Acoustic, nanomechanical, molecular and electromagnetic
Sending information by nanomolecular and electromagnetic methods
Molecular method is the sending and receiving of information encoded in molecules , while electromagnetic communication is sending and receiving electromagnetic radiation from various nano-equipment . These methods are molecular method and electromagnetic method are among the wireless methods . In the electromagnetic communication, electromagnetic communication between the nano- sensors is dependent on the development and construction of two major parts, nano-antennas and transceivers for it in Mqayas nanotubes, graphene-based antennas to transmit EM waves are used. Graphene is a very thin monoatomic plate of confined carbon atoms placed on a crystal lattice . Due to the very low dimensions of nano-sensors, nano-antennas to be able to The operating frequency must be very high. However, the use of graphene greatly helps to solve this problem.
Nano antennas and nano communication devices
The antenna is considered as the primary means of absorbing electromagnetic waves in space and has its own engineering knowledge, which is very developed and extensive . In general, in order to receive the electromagnetic wave in space, the dimensions of the antenna must be in the order of the size of the input wavelength to its surface. Of nano-technology includes components and tools that one of them is about one to several hundred nanometers. On this basis, if we are to antennas used in parts of nanoparticles in the range should be expected electromagnetic waves used in communications systems and equipment around several tens of THz which in turn includes the wavelength region of infrared, visible and ultraviolet will be .
Conclusion :
Data transfer between nano-sensors can increase the capabilities and applications of nano-devices compared to their single operating mode in both complexity and range of performance. This complex and flawless process with a wide coverage range can be called Nano (Data_Telecommunication) or Nano_Telecommunication.
