We observe closely that future will have graphene smartphone. Graphene is a material that will be exploited for a series of disruptive, revolutionary technologies. It comes from graphite, which is in pencils, but it is an infinitesimal part, that is an atom, isolated in the laboratory only a decade ago. The reason for its disruptive reach is soon said: As an atom is ultra thin, but it is harder than steel over 200 times. In electronic field can do sparks, thanks to its flexibility, transparency and conductivity (i.e. leads more electrical current than copper). Ultimately, it costs very little: being a material from carbon, much more available in nature than the current and expensive tantalum, cobalt, gold, silver, magnesium, bromine, nickel etc. that we find in smartphones. Didn’t you think there were so many? Well, let’s go back to focusing on the graphene smartphone.
From several parts, research has flourished on this material which has laid the premises for the population to have a day at the disposal of revolutionary products. But it comes from asking:
When will we see the first smartphones based on graphene?
At Mobile World Congress 2018 We have witnessed a whole pavilion dedicated to the applications of graphene in the technology field. We have seen experiments in various fields that have astonished the audience of curious: from cameras that see the invisible, to filters to make drinking water, passing through revolutionary smartphone batteries, ultrafast data transmission systems and solar cells With a much improved efficiency ratio.
But, the question: “When will we see a smartphone based on graphene?” arose spontaneously immediately after the closing of the Barcelona event.
There are currently more than 50,000 patents registered with WIPO in the United States concerning technologies related to graphene.
In fact, so many of those patents have not yet found a fulfillment. The products on the market pertaining to smartphones that use stably the graphene are few. The first that we remember are the earphones of the Chinese house Xiao Mi Pro HD, which contain a diaphragm of graphene to speed up the transmission of the audio signal to 100% and without leakage. Another product on the market that uses graphene are nanocase covers that can cool the batteries of smartphones thanks to the polymers of this material that dissipate the heat outside.
But that’s not enough to satisfy the consumers ‘ belly. Perhaps the most exciting uses of graphene are coming right from the batteries for smartphones, and it seems that Samsung, Apple and Huawei are close to release some prototypes, although starting from different searches (always with nanocase in the middle). Then there is also the graphene in the next flexible or foldable screens always built by Samsung and LG, but we will not see them before the end of the year 2018.
The technological sector that will benefit more
Given that the graphene will not replace the dear old silicon (without which we would not be talking about digital technology in general), already since the MWC 2018 we realized that the industry that will benefit most from this revolutionary material, well before telephony, is The 5g and the IoT. The application of graphene in telecommunications will solve many problems of speed and energy consumption in data transmission. The companies Ericsson, TIM and Comau have presented at MWC in Barcelona their project of Cloud robotics, bringing to light the potential of 5g in the perspective of the development of some innovative services IoT and smart solutions for Industry 4.0.
For the massive use in telephony, unfortunately, we must wait a few more years.
