Brain-Computer Interfaces (BCIs) for augmentation refer to systems that allow direct communication between the brain and external devices. These interfaces can be used to enhance various cognitive or sensory functions.
BCIs address issues related to human augmentation by providing a direct interface for enhancing cognitive functions like memory, learning speed, and sensory perception. They can also assist in restoring lost functions in individuals with disabilities.
BCIs typically involve implanting electrodes into specific regions of the brain, which then transmit neural signals to an external device. This device processes these signals and uses them to control or interact with other technologies, such as prosthetics, exoskeletons, or virtual reality systems.
Manufacturing BCIs involves precise microfabrication techniques for creating electrodes that can be implanted into the brain. These processes require highly specialized equipment and cleanroom facilities to ensure sterility and precision.
The build process starts with designing the implantable device, followed by fabricating the electrodes using materials like silicon or metal alloys. The devices are then tested in vitro before clinical trials on animals and eventually humans.
Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking. Power consumption during operation can be managed with efficient design but remains a challenge for long-term wearability.
