Current obstacles

  • Few participantsData from one or a few people can't show how well it works across many.
  • Complex surgery and wiringA wire from skull to chest adds surgery steps and more things that can break.

Physics limits

  • The brain walls off foreign objectsWithin weeks, support cells wrap anything pushed into brain tissue in scar, moving neurons away from electrode tips. On most penetrating implants, recorded signals fade over months to years.
  • Heat caps the data rateImplants may warm nearby brain tissue by only about 1 °C. That fixes the power budget for amplifiers and radio, which limits how many channels can be read and sent out wirelessly.
  • Decoders need lots of practice dataWith a few hundred recorded neurons, a speech decoder must learn each person's patterns from hours of attempted speech, and errors rise as the vocabulary grows.

How it works

1. Implant

Implant over speech areas

Surgeons insert the electrode piece into brain areas that control speech and hand movement.

2. Transmit

Wire to a chest unit

A wire under the skin carries signals to a chest unit that sends them wirelessly outside.

3. Decode

Brain activity to speech

AI trained on attempted speech turns brain activity into words and a synthetic voice.

Connexus brain implant, restoring speech

Austin company building Connexus, a high-data brain implant with 421 tiny wire electrodes and a wireless unit in the chest, first to give a voice back to people who can't speak. Its FDA-approved first trial began in Jun 2026.

  • First human test in May 2025: Connexus was placed for about 10 minutes during epilepsy surgery and recorded brain activity.
  • First trial patient implanted 17 Jun 2026; in Sep 2026 she used it to produce speech in real time.
