Graphene gets touted as a “wonder material” because of its unique properties. Here are five potential real-world uses. Graphene is 200 times stronger than steeland lighter than paper and often referred to as a wonder material. But what can this substance actually do?
Fortunately, graphene had a chance to shine at last month’s Mobile World Congress trade show in Barcelona. Buried away at the furthest point from the entrance to the convention center was the Graphene Pavilion, where around 25 different graphene-based research projects, including robotics and wearables, were being shown off.In the coming years some of these applications will go commercial and we’ll start to see graphene cropping up in phones, wearables, and other technology.
Graphene is a thin layer of pure carbon atoms tightly packed in a honeycomb structure. It isn’t manufactured, but instead is extracted from graphite — a process scientists only succeeded in developing in 2004. The result is a 2D substance that has a number of unusual and desirable traits, including being extraordinarily thin, strong and flexible.
Europe is where graphene was first isolated, and so convinced is the EU by its potential that it’s the basis of the bloc’s biggest research initiative. The billion-euro Graphene Flagship program, which hosted the Graphene Pavilion, is dedicated to finding ways in which the material can be brought to market.
Here’s how graphene may be used in the future.
Graphene may have been hidden away at the back of the show this time around, but in the coming years, it could be responsible for some dramatic upgrades to phone technology. As well as being flexible enough to be incorporated into bendable phones in the form of antennas or touch displays, it also has enormous potential for improving batteries — often our biggest gripe when it comes to our phones.Graphene can be built into the batteries themselves to improve energy storage and long-term performance, but it can also speed up energy transfer between a power source and battery exponentially. It acts as a sort of superhighway for charging, allowing energy to pass through it so quickly that researchers believe it can charge a phone in 7 seconds.
So how long will this seemingly magical technology take to show up? A decade? Kari Hjelt, head of innovation for Graphene Flagship, said it would take as little as two years.
“It’s still a young material, so we’re actually quite amazed how much it has developed in only 14 years,” he said. “The thing with the graphene is that it works in so many fields and in fantastic ways, so we have really picked the ones that are the most promising for Europe and for business.”
Phone technology is one obvious use, and 5G network tech is another — Ericsson used graphene in its own 5G demo at the show. But it’s not the only area where the material can make a difference.
One biomedical possibility for graphene is in the improvement of artificial limbs.
By embedding graphene-based nerve sensors within the top of the limbs, a person is able to sense and respond to contractions and other movements in muscles. That helps them control the motion and force of a robotic limb.
