Graphene Is Invading Our Brains

Earlier this year, researchers at the University of California, San Diego, made history with a revolutionary brain implant the thickness of Scotch tape.The implant, which uses graphene for the electrode material, allows scientists to monitor activity deep within the brain without the need for surface-penetrating probes or other more invasive procedures. 

It simply adhere to the brain’s surface under the skull and reads whats happening underneath.


Duygu Kuzum, a professor in the Department of Electrical and Computer Engineering at the UC San Diego Jacobs School of Engineering, and senior researcher on this project, commented:

“We are expanding the spatial reach of neural recordings with this technology. Even though our implant resides on the brain’s surface, its design goes beyond the limits of physical sensing in that it can infer neural activity from deeper layers.”

AI plays a crucial role in making these inferences, but without the 20 micrometer-wide graphene electrodes, nothing on this scale would have been even close to possible.

Graphene Started As A Science Experiment

Stories like this seem to be getting more abundant of late, indicating the turn of a critical corner in the story of graphene.

Every new substance goes through the same cycle. 

From experimental and expensive to commonplace and cheap, the transition from science project to mainstream commercial material can take years or even decades. 

For modern plastics, the same story began almost exactly 100 years prior to graphene with the advent of Bakelite in 1907. 


Since then, plastics have taken over the earth and are found in almost every mass produced consumer product in existence. 

Before plastics, aluminum was the wonder material of the early industrial age.

In the mid 19th century, builders of the Washington Monument even went so far as to incoporate it into the building’s cap, as aluminum of the day commended a higher price than gold.


Today, it’s the most abundant non synthetic material known to man.

With graphene, the story will be much the same, but the extent to which it evolves the products it’s used in will be far more profound. 

The neural implant described above was just one example. 

The Graphene Rechargeable Battery Could Take Less Than A Minute To Charge

Another example, one less exciting and far, far more impactful on modern life, is graphene applied to rechargeable battery technology. 

Right now there’s a company building lithium-free graphene-based rechargeable batteries in Brisbane Australia that are in a completely different performance category from anything on the open market. 

These batteries have 2-3 times the service life, 2-3 times the charge capacity, and up to 70 times the charge speed. 

You read the last figure correctly. That’s 70x faster to charge than the one in your phone, your tablet, or your EV — which means it takes less time to charge the battery to capacity than it will to finish this article. 

In fact, these batteries charge faster than you could fill a standard ICE fuel tank at the pump — which immediately eliminates the biggest hurdle stopping prospective EV buyers: charge delay. 

These graphene batteries are also fire-proof and so durable that they’ve continued to run after withstanding a point-blank shot from a rifle. 

Graphene Batteries Are The Gasoline To Lithium’s Coal

Like I said, there is nothing in the lithium realm that comes close. 

And to be lithium-free in a world where the lithium refining industry is all but owned by the Chinese Communist Party is a benefit of its own kind. 

So why aren’t these batteries dominating the market already?

Simple… Because they’re still in testing. 

This company is slowly developing and perfecting the product while ramping up early run production. 

Soon enough, these batteries could start to trickle their way into small consumer tech products. 

Eventually, however, it’s quite conceivable that they’ll find their way into institutional and consumer operated electric vehicles. 

The company behind it all is small and quiet, but it’s focused on graphene as a product and as you’ve probably been able to tell, graphene has a huge role to play in the future. 

The Best Time To Buy Is When Nobody Is Talking about It

At the moment, however, things are still quiet. 

This company trades on two North American exchanges for less than $100M, even though its work with graphene batteries easily has multi-billion dollar potential. 

I first introduced my readers to this company last year, and needless to say, a lot has changed since then. 

Today may be the best time ever to get exposed to the graphene battery sector, before it becomes the next big thing in consumer tech.
