Your Future Brain-Machine Implant: Ultrasonic Neural  Dust

Imagine thousands of particle-sized CMOS chips living in  your brain.

Remember those slender gleaming spikes Keanu Reeves and pals jacked into the  backs of their noggins to go virtual-reality tripping in The Matrix?  That’s certainly an image: prong-to-brain networking, your neurons serviced by  skewer.

But then the movies — what can you do? The future of brain-machine  interfaces may be less, umm, visible if cutting-edge research by scientists at  the University of California Berkeley proves viable.

One of the biggest challenges for brain-machine interfaces (BMI) is how to  create one you could use indefinitely (like for a lifetime). Even in The  Matrix, connecting to the cloud seems awfully inconvenient: sit back in a  chair, stab yourself in the skull. Existing real-world BMI systems are clumsier  still. As KurzweilAI notes: “Current BMI systems are also limited to  several hundred implantable recording sites, they generate tissue responses  around the implanted electrodes that degrade recording performance over time,  and are limited to months to a few years.”

What if, instead, we built entire armies of tiny dust-sized sensor nodes that  could be implanted in the brain (though not autonomously — this isn’t  colonize-your-brain-stem time yet) to facilitate communication of whatever sort,  in this case keeping high-res tabs on neural signals and relaying data back to  aggregation devices via ultrasound?

Here’s how it might work: First you pop through the skull and the brain’s  dura (the membrane surrounding the brain), dipping into the brain’s neural sea  itself, roughly two millimeters down, where you position thousands of  low-powered CMOS chips (the “neural dust,” each as tiny as millionths of a  meter) to begin capturing neural signals using electrodes and piezoelectric  sensors, which convert the data to ultrasonic signals. Those signals are then  picked up by a sub-dural transceiver (sitting just above the “dust” chips and  simultaneously powering them ultrasonically), which relays the data to an  external transceiver resting just outside the skull (ASIC, memory, battery,  long-range transmitter), which in turn communicates wirelessly with whatever  computing device.

Like most futurist notions, this one hasn’t been tested yet — it’s just a formal proposal —  but it’s another fascinating glimpse into where we might be headed, bypassing  clumsy literal BMI head-jacks for micro-scale interfaces that  would link us, wire-free, to future galaxies of virtual information.

  1. Remote neural monitoring satellite harassment terrorism and human experimentation of Brazil

    My name is Marisa am a victim of human minds trafficking ring operating in southers Brazil, i have an intracranial implant an i’m being tortured. I need help to save my life means to break free of this harassment. Criminals step into the human brain 24hs the connection an come from several People at the same time, reading the visual córtex through the computer brain interface using mobile phone masts and satellite. The mental grocery prison of life, torture or brain radar signature.There is a software created and based on neurosciense of the brain and humam mind that is being used to torture People. This weapons uses Neuroeletronicas brain frequency of 3hz to 50hz distance to torture victim by sending intracranial voices plague victims who be come human guinea pigs in the hands of entire gangs that are usurping these bodies victims need to try a faraday cage p try to get rid of this harassment.

    Please help me blocking remote neural monitoring

  2. I too am also a victim of this type of technology being implemented by the us warfare department it has been going on for over a decade for and of course I have been labeled insane I have not even looked on the web lately being the last five years I see now there is a lot of talk of this happening it is only a matter of time till it comes to the light of day hang in there is all I can say to you.
