Neuralink’s Brain-Computer Interface (BCI) is a technology designed to establish direct communication between the human brain and external devices. It involves the implantation of microelectrodes into the brain to capture neural signals, which are then translated into commands that can control various devices.
BCI technology addresses the challenge of enabling individuals with severe paralysis to regain some level of independence and ability to communicate, as well as potentially aiding in mental health treatments by providing a non-invasive way to monitor brain activity.
The BCI system includes implanted electrodes that are connected to a small device placed on the scalp. These electrodes record neural activity and transmit it wirelessly to an external receiver. The data is processed by machine learning algorithms to decode the brain’s signals, which are then used to control external devices such as computers or prosthetic limbs.
The manufacturing process involves the creation of microelectrodes that can safely interface with neural tissue, followed by their precise implantation into specific regions of the brain. This requires advanced materials and highly specialized equipment.
The build process includes designing and fabricating the electrodes, sterilization to ensure biocompatibility, implanting them in the brain, and connecting them to a wireless receiver on the scalp. The entire system must be tested for safety and functionality before use.
Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking. Power consumption during operation is relatively low but could increase with more complex data processing requirements.
