The specs are pretty wild:
Form Factor: It rests on the brain "like a piece of wet tissue paper."
Resolution: 65,536 electrodes with 1,024 simultaneous recording channels.
Bandwidth: 100 Mbps wireless link (custom ultra-wideband radio).
Power: Fully wireless via an external relay station.
The differentiator here seems to be the non-penetrating approach. Unlike Utah arrays or Neuralink threads that penetrate the cortex, this sits on top, which theoretically minimizes tissue scarring/reaction while maintaining high data throughput (100x current wireless BCIs).
