The Neuralink N1 chip is a brain-computer interface (BCI) device with 1,024 electrodes across 64 ultra-thin, flexible threads that are surgically implanted into the brain by a robotic system. The coin-sized implant records neural activity, processes the signals, and transmits them wirelessly via Bluetooth to a connected app, which allows users to control external devices like a computer cursor with their thoughts. It is designed to be fully implantable, hermetically sealed, and wirelessly charged.
