Brain‑computer interface (BCI) technology lets the brain communicate directly with electronic equipment by bypassing the body. Electrodes placed on or inside the brain record electrical pulses, which a brain chip processes and an internal control unit transmits wirelessly to an external device such as a tablet or prosthetic. Artificial‑intelligence algorithms filter the noisy brain data and isolate specific neural instructions. Devices range from non‑invasive scalp‑based systems to invasive implants that sit on or within the cortex.

The State of the Industry

U.S. companies have raised roughly $2.75 billion for BCI development, while Chinese brain‑chip startups saw funding more than double in 2025 compared with the prior year. China’s 15th five‑year plan lists BCI as one of six “strategic industries of the future,” pairing policy support with clearer guidelines, faster clinical‑trial reviews, and a $165 million brain‑science fund. Shanghai‑based NeuroXess is constructing a manufacturing facility capable of producing 10,000 devices per year, signaling a shift from research prototypes to mass‑market hardware.

Clinical Trials and Case Studies

Since October 2025, Mr. Zhang, a paralyzed patient, has used a NeuroXess BCI that employs a strip of cortical electrodes connected to an internal control unit transmitting data wirelessly. The system enables him to operate external devices, and collaborations with companies such as Xiaomi aim to extend control to smart‑home appliances. Future trial goals include linking the implant to robotic exoskeletons so patients can regain mobility.

Regulatory and Ethical Challenges

Invasive implants carry the risk of scar tissue formation, which can damage brain cells and block neural signals, degrading device performance over time. BCI devices are classified as Class III medical devices, the most stringent regulatory category, demanding extensive safety and efficacy data before approval. Concerns also surround neural privacy, data access, potential military or mind‑control misuse, and unresolved questions about insurance coverage and long‑term commercial viability.

Takeaways

BCI technology translates brain electrical activity into commands for electronic devices using electrodes and AI to filter noisy signals.
US firms have attracted about $2.75 billion in venture capital, while Chinese brain‑chip startups saw funding more than double in 2025 and receive policy backing in the 15th Five‑Year Plan.
Shanghai startup NeuroXess is scaling production to 10,000 devices annually and already has a paralyzed patient, Mr. Zhang, using an implanted cortical strip to control external systems.
Invasive BCI implants face safety hurdles such as scar tissue formation that degrades signal quality, and they are classified as Class III medical devices, making regulatory approval difficult.
Concerns about neural privacy, data access, potential military misuse, and uncertain insurance coverage create ethical and commercial challenges for the emerging BCI market.

Frequently Asked Questions

How does scar tissue affect the performance of invasive BCI implants?

Scar tissue forms around implanted electrodes, insulating them and reducing signal fidelity; this degradation can impair the device’s ability to read neural commands accurately and may also damage surrounding brain cells, raising safety and efficacy concerns for long‑term use.

What regulatory category do BCI devices fall under and why is it significant?

BCI devices are classified as Class III medical devices, the highest risk category, requiring extensive clinical data, rigorous safety testing, and lengthy approval processes, which slows market entry and raises development costs.

- This is Mr.
Zhang. He asked us not to film
his face for privacy reasons.
A little over eight years ago,
an accident left him
paralyzed from the neck down,
but here, he's controlling
his wheelchair with his mind.
- He's even got a few
tricks up his sleeve.
Last year, Mr. Zhang had surgery
to get a brain-computer interface,
or BCI from a Shanghai-based
startup called NeuroXess.
- Training is part of a new wave
of clinical trials in China,
hoping to make the next
breakthrough in BCI tech.
- US companies certainly had
a head start in developing
these systems and testing
these systems in humans,
but China is certainly
catching up very rapidly.
- The race to get BCI's to market is on
and the stakes for one
well-known tech CEO are high.
Like saving humanity from
the robocalypse high.
- Ultimately, I think
this helps mitigate the
civilizational risk of
artificial intelligence.
- AI doom scenario aside,
there's a chance BCI's could move
beyond just medical purposes
and further enmesh humans and technology.
But first, they've gotta get to market.
- Tiny electrodes are
carefully cemented to the scalp
to detect and record the delicate
pulses from the human brain.
- There's been a lot of
buzz around brain-computer
interfaces in the past few years,
but the technology behind
them isn't all that new.
- So a brain-computer interface
is a piece of technology
that allows your brain
to communicate directly
with a computer
or another sort of piece
of electronic equipment
bypassing the rest of the body.
- The term brain-computer
interface was coined in the 1970s
by an American scientist who showed
that one could take electrical
signals measured by an EEG
and map it onto patterns
and then decode how that
corresponds to movement.
- It wasn't until sort of
the early 2000s
that we got into humans using these chips
to read the activity in human brains.
- Over the past few years,
it's really entered
mainstream consciousness.
Thanks in no small part to the enthusiasm
of tech billionaires,
but we are at a point where
are moving fast in clinical trials
and really working
towards bringing a product
to commercial use.
- BCI's work like this:
Everything you do,
whether that's speak, eat
or move your hand is driven
by neurons in your brain.
Those neurons send electrical signals
to each other to create action.
BCI's read and decode those signals
to control an external
device like a tablet
or prosthetic limb.
BCI's come in varying
degrees of invasiveness.
Some need to be surgically implanted
and either stick into the brain
or sit right on top of it.
Others are placed on top of the scalp.
Regardless of how you measure
it, brain data is noisy.
That's where AI comes in. BCI
companies use algorithms to
filter out background chatter
and accurately identify
the brain's instructions.
- The vast rich amount of data
that they collect can be super
helpful in helping scientists
understand the human brain better.
And a lot of researchers
believe that this kind
of data will help AI researchers
build totally different
kind of artificial intelligence systems.
- In the US, it's estimated
that BCI companies have raised
$2.75 billion collectively.
- Chinese and European
companies have raised maybe a
fraction of that.
- Even so, the Chinese
sector is growing. Funding
for Chinese brain chip startups
more than doubled in 2025
compared to the year before.
And in March of 2026, China
approved its first invasive BCI
for commercial use, a signal
that it's betting big on this tech.
- My name's Tiger Tao,
and actually Tiger is
the direct translation
of my first name Hu in Chinese.
So it has nothing to
do with my personality.
- Over the past few years,
NeuroXess has been experimenting
with different approaches to BCI's.
- I was hoping that maybe
you could bring the Marva
- The device uses a strip of
electrodes that sits on top
of the cortex that can
record signals in the brain.
Those electrodes are
connected to a brain chip
that does all the signal
processing that's attached
to an internal control unit
that processes and wirelessly
transmits data to a computer.
It also houses the battery
- More than 50 patients have
tested different versions
of NeuroXess's technology, but Mr.
Zhang has lived with it the
longest since October of 2025.
He spends several hours a day training
to learn new skills with his BCI.
- It's also interesting
that NeuroXess has a
collaboration with Xiaomi, one
of the leading home
appliances companies in China
to integrate
its BCI with a whole universe
of smart home devices.
- Other startups have similar partnerships
with tech companies so
that patients can start
to control their devices with their minds.
Mr. Zhang is also training
to control a robotic
exoskeleton on his hand.
According to Tao, this sort
of tech could one day
help Mr. Zhang walk again.
Mr. Zhang will have this
implant for an entire year,
which is critical to test its long-term
safety and effectiveness.
After that, Mr. Zhang could remove
or keep the BCI,
which NeuroXess claims
could last three years.
- In a sense, it can be a
ticking time bomb when something
is put in the human brain,
which is very sensitive area of the body.
- That's because over time,
the brain forms scar tissue
around the implant, which
can damage brain cells
and block signals to the device.
NeuroXess opted for a less
invasive strip of electrodes
to help reduce scarring
and maintain a good signal.
One challenge? The bar for
regulatory approval is very high.
- This is gonna be classified
as class III medical device, which
is the hardest to get
in terms of approval.
- But they've got a helping hand.
Every five years, China's top
officials release an outline
for key areas of economic
and social development.
That support can catapult nascent
industries to new heights.
For example, China's
highlighted new energy vehicles
for investment over the past few decades,
and today they dominate most
of the global EV market.
- In the 15th five year plan,
BCI was designated as one
of six strategic industries of the future.
- That means clearer guidelines,
faster clinical trial reviews
and better coordination.
Oh, and a $165 million brain science
fund to back the fledgling industry.
- So while venture funding
for these BCI companies are
relatively limited compared
to their US peers, this kind
of policy support really
helps them accelerate their
development of BCI technology.
- The biggest test will be
whether BCI's can actually be a
viable business
and whether it can live
up to all its hype,
all its promises when it's rolled out in a
commercial, real world setting.
- There is a big open question
of how these are going
to be paid for, what sort
of insurance coverage
will look like, whether
that will be sufficient
to to cover the costs.
- BCI's
are unsurprisingly expensive.
In July 2025, Bloomberg reported
that Neuralink estimates each
surgery will bring in $50,000.
NeuroXess hasn't announced an estimate,
but they've already broken ground on a
manufacturing facility
the company says will make
10,000 devices a year.
- I think then, you know, companies
and investors are gonna have
to see how, you know, large,
they really need this market
to be. Will it be sufficient
to only use this as a medical device?
Or will investors want more of return
and want this technology to be available
or marketed more broadly?
- Mass adoption of this
tech, whether invasive
or non-invasive, raises
questions about the future
of neural privacy.
- As this technology becomes
more widely available,
which you know, many people
think it will, there are sort
of questions to be raised
about who has access
to this data and what happens to it.
- In response to the rapid
acceleration of BCI tech,
some jurisdictions are passing laws
to protect neural privacy.
- There are fears that
ultimately BCI will be used
or abused to alter people's
consciousness against their
wills or even be deployed
in a military setting
to create soldiers with
enhanced cognitive abilities.
- Those nightmare scenarios
have some basis in
reality. In the US,
the CIA ran illegal experiments to try
to unlock mind control
during the Cold War.
And more recently, the US's
primary military research arm,
DARPA, has funded studies
into BCI's that could allow
for hands-free control of drones.
China has also funded brain research
for military applications
For now,
BCI trials are helping people
with disabilities regain
their independence
for everyday tasks.
But Mr. Zhang is thinking beyond that.
