It seemed that the revolutionary technology

Graphene was originally made in a rather unusual way, Humphreys explained. Geim and Novoselov created it by sticking sticky tape on pieces of graphite and peeling off layers until they had a material one atom thick.
“But this can only produce a tiny flake, a few millimeters wide,” the professor added. “It’s impossible to make electronics from such pieces. For functional devices, you need plates of material at least 15 cm thick.”
IBM, Samsung and Intel have collectively spent billions trying to scale up graphene production in a form suitable for production and in the quantities needed, but their attempts have been unsuccessful, Humphreys says.
As a result, the graphene revolution was delayed, but there paraguay number data have been recent signs that it is too early to give up on the technology's promising prospects.
The professor believes that the market could be given a second lease of life in the future thanks to a breakthrough in creating graphene-based devices. Humphreys and colleagues made a key discovery by discovering that the technology used to produce electronic components based on gallium nitride can also be used to produce graphene on a large scale.
“We used some of the first graphene obtained in this way to create a sensor that can detect magnetic fields,” Humphreys said.
Since then, the professor and his team have founded a subsidiary, Paragraf, in Somersham, Cambridgeshire, England. The company is one of the first in the world to mass-produce graphene-based devices. Two reactors, shaped like pizza ovens, produce enough graphene to make 150,000 devices a day.
Paragraf uses the devices for two purposes. First, for sensors that measure magnetic fields. They can be used to detect faulty batteries in electric scooters and e-bikes, preventing fires.
A second sensor could detect bacterial or viral infection to decide whether to prescribe antibiotics in case of illness. Humphreys believes that biosensors could diagnose sepsis in minutes.
Humphreys added that graphene devices are likely to consume less energy.
