Graphene alters the Internet of Things (TOT) in the future significantly

Hexagonal single layer structure of graphene

Aeglephysics.com -- Graphene, a material composed by a single layer of carbon atomic bonding hexagonally, provides a unique and promising properties. One of them is the higher of electrical conductivity than that is owned by copper. Throughout that, graphene is considered as the material which can change significantly the way we use internet in the future.

Today’s things are mostly related to the internet. Smartphone, computer, television and many of electrical devices are connected to the internet. The way we use these devices is called remote sensing, while the things that are remoted throughout internet are called the Internet of Things (TOT).
Graphene material, which was firstly obtained by Prof. Kostya Novoselov of the University of Manchester in 2004, shows significant effects to the world of communication. Scientists and researchers from the University of Manchester have been able to develop new method to enhance the function of graphene. By layering the graphene and graphene oxide (graphene oxide is a derivative from graphene), the scientists developed the new characteristics which can be embedded into Radio-Frequency Identification (RFID). This implies to the potential in altering the whole aspect of internet of things.

This heterogeneous layer of graphene-graphene oxide generates sequences of Van der Waals bonding, implying to the presence of electrical inductance. As a result, the material could be used as humidity sensors for remote sensing, with the ability to connect any wireless network. So, electrical inductance not only provide received-like ability to connect any wireless network, but also it provides energy throughout the bonding. Consequently, we could have a receiver without needing to be charged regarding its power.

This sensor based on graphene-graphene oxide could be fabricated in industrial scale. It clearly can be understood that both graphene and graphene oxide are single layer material, so when they are fabricated, they are just a brick with cement. Technically speaking, it is similar to a child build wall with white and black Legos, which are illustrated as respectively graphene and graphene oxide.
