The brief
- Brain Interchange is the first fully implanted wireless BCI combining decoding and stimulation.
- Three patients implanted in UW trial show motor recovery; patient played Pong with neural control.
- FDA Breakthrough designations for stroke recovery (Apr 2026) and communication restoration (Aug 2026).
Technical approach
Decode and stimulate in one implant
Microelectrodes both decode motor intention and deliver stimulation for recovery.
No scalp wires or percutaneous connectors
Wireless power and communication eliminate infection risk and allow normal movement.
Pairing decoding with rehab-triggered stimulation
BCI detects movement intent and delivers stimulation to enhance neuroplasticity.
