Literal Smart Dust Opens Brain-Computer Pathway to “Spy on Your Brain”
Source: Activist Post Some might have heard about Smart Dust; nanoparticles that can be employed as sensor networks for a rangeof security and environmental applications. Now, however, literal Smart Dust for the brain is being proposed as the next step toward establishing a brain-computer interface. The system is officially called “neural dust” and works to “monitor the brain from the inside.” Inventors are attempting to overcome the hurdle of how to best implant sensors that can remain over the course of one’s life. Researchers at Berkeley Engineering believe they have found a novel way to achieve this: This paper explores the fundamental system design trade-offs and ultimate size, power, and bandwidth scaling limits of neural recording systems. A network of tiny implantable sensors could function like an MRI inside the brain, recording data on nearby neurons and transmitting it back out. However, this is the first time that there is a working plan to apply Smart Dust to the human brain.
