Bendable mobile phones, quick-charge batteries and unbreakable touch screens — technology firms are racing to harness the potential of graphene, a wonder material that scientists say could transform consumer electronics.
A fine sheet of pure carbon, graphene is as thin as an atom, making it the skinniest material known.
At the same time though, it is 100 times stronger than steel, hugely pliable and can conduct electricity and heat better than anything else.
“There are other materials which do have one of those properties each,” said physicist Kostya Novoselov — who first isolated graphene in 2004 — last week at the Mobile World Congress, the sector’s biggest trade fair, in Barcelona.
“What is amazing here is that all those qualities are combined in one simple crystal,” he said. “Of course that immediately leaves us with a number of possible applications.”
Novoselov, a Russian-born British citizen, and his colleague at Manchester University, Andre Geim, won the Nobel Prize for their work with graphene, sparking a flurry of interest in the new material.
The number of patents involving graphene soared from less than 50 in 2004 to about 9,000 in 2014, according to Andrew Garland of research firm Future Markets, who puts out a twice-yearly report on the material.
“Most [of the patents] are in electronics,” he said.
Samsung Electronics Co, the world’s No. 1 smartphone maker, has taken out the most graphene patents — more than 490 — followed by China’s Ocean’s King Lighting Science & Technology Co (海洋王照明) and IBM Corp.
While its real-world uses so far remain modest, research into possible applications for the material picked up steam in Europe after the EU set aside 1 billion euros (US$1.1 billion at current exchange rates) in 2013 to be spent over 10 years to investigate.
“We believe we require another 10 years to get to the point where a lot of devices will start being on the market,” said Andrea Ferrari, director of the Cambridge Graphene Center at the University of Cambridge in England.
The trade fair in Barcelona for the first time had a pavilion dedicated to graphene research centers and start-ups, a sign of the growing importance of the material.
Graphene is so pliable scientists predict it will one day make flexible phones possible.
British firm FlexEnable Ltd showcased a smartwatch prototype made using graphene that wraps around a user’s wrist, while British tech firm Zap&Go Corp displayed a graphene charger for mobile phones and tablets that takes just five minutes to fully load with power.
Graphene is so strong and thin that researchers believe they will one day be able to use it to make unbreakable screens for mobile devices.
“With just a few kilos you can replace all the touchscreens in the word. With just a few layers on top of each other you can support an elephant,” the Italian Institute of Technology’s Graphene Labs director Vittorio Pellegrini said. “Graphene is really a material that allows our imagination to fly. There is no limit to what you can do.”
CHIP WAR: Tariffs on Taiwanese chips would prompt companies to move their factories, but not necessarily to the US, unleashing a ‘global cross-sector tariff war’ US President Donald Trump would “shoot himself in the foot” if he follows through on his recent pledge to impose higher tariffs on Taiwanese and other foreign semiconductors entering the US, analysts said. Trump’s plans to raise tariffs on chips manufactured in Taiwan to as high as 100 percent would backfire, macroeconomist Henry Wu (吳嘉隆) said. He would “shoot himself in the foot,” Wu said on Saturday, as such economic measures would lead Taiwanese chip suppliers to pass on additional costs to their US clients and consumers, and ultimately cause another wave of inflation. Trump has claimed that Taiwan took up to
A start-up in Mexico is trying to help get a handle on one coastal city’s plastic waste problem by converting it into gasoline, diesel and other fuels. With less than 10 percent of the world’s plastics being recycled, Petgas’ idea is that rather than letting discarded plastic become waste, it can become productive again as fuel. Petgas developed a machine in the port city of Boca del Rio that uses pyrolysis, a thermodynamic process that heats plastics in the absence of oxygen, breaking it down to produce gasoline, diesel, kerosene, paraffin and coke. Petgas chief technology officer Carlos Parraguirre Diaz said that in
Japan intends to closely monitor the impact on its currency of US President Donald Trump’s new tariffs and is worried about the international fallout from the trade imposts, Japanese Minister of Finance Katsunobu Kato said. “We need to carefully see how the exchange rate and other factors will be affected and what form US monetary policy will take in the future,” Kato said yesterday in an interview with Fuji Television. Japan is very concerned about how the tariffs might impact the global economy, he added. Kato spoke as nations and firms brace for potential repercussions after Trump unleashed the first salvo of
SUPPORT: The government said it would help firms deal with supply disruptions, after Trump signed orders imposing tariffs of 25 percent on imports from Canada and Mexico The government pledged to help companies with operations in Mexico, such as iPhone assembler Hon Hai Precision Industry Co (鴻海精密), also known as Foxconn Technology Group (富士康科技集團), shift production lines and investment if needed to deal with higher US tariffs. The Ministry of Economic Affairs yesterday announced measures to help local firms cope with the US tariff increases on Canada, Mexico, China and other potential areas. The ministry said that it would establish an investment and trade service center in the US to help Taiwanese firms assess the investment environment in different US states, plan supply chain relocation strategies and
