Australian scientists have achieved an unprecedented breakthrough that blurs the line between science fiction and reality: They have created an artificial intelligence system capable of reading human thoughts via brainwaves. This cutting-edge technology can transform electrical signals from the brain into meaningful data, potentially enabling machines to interpret what people are thinking without spoken language or physical actions being necessary. AI models have proven their worth in deciphering complex thoughts non-invasively, opening the way to revolutionary applications in healthcare, communication and brain-computer interfaces. Though still in its experimental stage, experts believe this technology could one day assist individuals with speech or mobility impairments in communicating more easily--raising both excitement and ethical concerns regarding privacy issues as well as human-AI interactions in the future.

In a significant step forward for brain-computer links, engineers at the University of Technology Sydney say their new A.I. can turn raw brain waves into text. Although the work is very early, the system already translates EEG data – usually used to check brain health – into clear sentences while the volunteer remains silent.

How Does the Thought-Decoding AI Work?

 

  • Led by PhD researcher Charles (Jinzhao) Zhou, the team trains deep-learning models on large sets of EEG recordings
  • A 128-electrode cap collects the data in a painless, skin-friendly way.
  • On one trial, the system printed the thought, “I am jumping happily, it’s just me.” — without any speech or movement from the volunteer.

 

The system filters out “noise” in the brainwave data to detect unique brain signal patterns corresponding to specific words or phrases.

Why This Matters: Non-Invasive and Versatile

Unlike Elon Musk’s Neuralink, which requires surgery, UTS’s approach leaves the skull untouched.

“We can’t get very precise because with non-invasive, you can’t actually put it into that part of the brain that decodes words,” said Professor Chin-Teng Lin, one of the project’s leads.

Despite limitations in precision, the potential applications are massive:

 

  • Stroke rehabilitation
  • Speech therapy for autism
  • Restoring communication in paralysis patients

 

Similar Innovations Worldwide

This isn’t the only research combining AI and EEG:

 

  • In April 2025, Mass General Brigham released a system that scans overnight brain waves and warns doctors about future memory loss.
  • It flagged 85 percent of high-risk patientseveryone doctors already suspectedwith a total accuracy of 77 percent.

 

What’s Next?

Right now the UTS system knows only a handful of words, but researchers plan to feed it larger datasets so it handles full sentences. If that works, people might one day type entire paragraphs by thought alone, a breakthrough that could change daily life for millions with speech and movement challenges.
