The Link is Neuralink's flagship brain-computer interface device. It consists of a small, coin-sized chip designed to be implanted directly into the brain. This chip contains numerous microelectrodes capable of detecting and transmitting neural signals.

The Link is wireless and rechargeable, eliminating the need for external wires or frequent battery replacements. It processes and transmits data in real-time, allowing for rapid communication between the brain and external devices.

Engineering and Design

Neuralink's engineering team has focused on creating a compact and efficient device. The Link incorporates custom-designed chips and circuitry to handle complex signal processing tasks.

The device is hermetically sealed to protect its sensitive components from the body's internal environment. This design ensures long-term functionality and reduces the risk of infection or rejection.

Neuralink has prioritized miniaturization, aiming to make the implant as unobtrusive as possible while maximizing its capabilities.

Electrodes and Threads

A key innovation in Neuralink's technology is the use of ultra-thin, flexible threads to connect the chip to the brain. These threads are significantly thinner than a human hair, measuring just 4 to 6 μm in diameter.

Each thread contains multiple electrodes capable of detecting electrical signals from neurons. The Link device can support over 1,000 of these electrode-laden threads.

The flexibility and small size of the threads are crucial for minimizing damage to brain tissue during and after implantation. This design allows for a more extensive and precise interface with neural networks.

Surgical Robot and Installation

Neuralink has developed a specialized surgical robot, known as the R1, to perform the delicate task of implanting the threads into the brain. This robot is designed to insert the threads with extreme precision, avoiding blood vessels to minimize tissue damage.

The R1 robot uses advanced imaging and machine learning algorithms to plan and execute the implantation procedure. It can insert multiple threads per minute, significantly reducing surgery time.

The automated nature of the implantation process aims to make the procedure more consistent and scalable, potentially allowing for wider adoption of the technology in the future.
