DARPA Funds Wearable Brain Interfaces

DARPA funds Next-Generation Nonsurgical Neurotechnology (N3) program to make wearable brain interfaces.

Battelle Memorial Institute, Carnegie Mellon University, Johns Hopkins University Applied Physics Laboratory, Palo Alto Research Center (PARC), Rice University, and Teledyne Scientific are leading multidisciplinary teams to develop high-resolution, bidirectional brain-machine interfaces for use by able-bodied service members. These wearable interfaces could ultimately enable diverse national security applications such as control of active cyber defense systems and swarms of unmanned aerial vehicles, or teaming with computer systems to multitask during complex missions.

The N3 teams are pursuing a range of approaches that use optics, acoustics, and electromagnetics to record neural activity and/or send signals back to the brain at high speed and resolution. The research is split between two tracks. Teams are pursuing either completely noninvasive interfaces that are entirely external to the body or minutely invasive interface systems that include nanotransducers that can be temporarily and nonsurgically delivered to the brain to improve signal resolution.

* The Battelle team, under principal investigator Dr. Gaurav Sharma, aims to develop a minutely invasive interface system that pairs an external transceiver with electromagnetic nanotransducers that are nonsurgically delivered to neurons of interest. The nanotransducers would convert electrical signals from the neurons into magnetic signals that can be recorded and processed by the external transceiver, and vice versa, to enable bidirectional communication.

* The Carnegie Mellon University team, under principal investigator Dr. Pulkit Grover, aims to develop a completely noninvasive device that uses an acousto-optical approach to record from the brain and interfering electrical fields to write to specific neurons. The team will use ultrasound waves to guide light into and out of the brain to detect neural activity. The team’s write approach exploits the non-linear response of neurons to electric fields to enable localized stimulation of specific cell types.

* The Johns Hopkins University Applied Physics Laboratory team, under principal investigator Dr. David Blodgett, aims to develop a completely noninvasive, coherent optical system for recording from the brain. The system will directly measure optical path-length changes in neural tissue that correlate with neural activity.

* The PARC team, under principal investigator Dr. Krishnan Thyagarajan, aims to develop a completely noninvasive acousto-magnetic device for writing to the brain. Their approach pairs ultrasound waves with magnetic fields to generate localized electric currents for neuromodulation. The hybrid approach offers the potential for localized neuromodulation deeper in the brain.

* The Rice University team, under principal investigator Dr. Jacob Robinson, aims to develop a minutely invasive, bidirectional system for recording from and writing to the brain. For the recording function, the interface will use diffuse optical tomography to infer neural activity by measuring light scattering in neural tissue. To enable the write function, the team will use a magneto-genetic approach to make neurons sensitive to magnetic fields.

* The Teledyne team, under principal investigator Dr. Patrick Connolly, aims to develop a completely noninvasive, integrated device that uses micro optically pumped magnetometers to detect small, localized magnetic fields that correlate with neural activity. The team will use focused ultrasound for writing to neurons.

  1. It’s the bizzare love triangle between the military industrial complex, the Indian engineering service companies, and the Chinese us tech invasion force… you would think they would be enemies… but somehow in some strangely hidden and corrupt way they are married in a ways that make no sense… like why would you let advanced espionage spying tech leak to the other and share information with mutual enemies? You sit around in a military industrial complex company… somehow they are the right arm of the same people trying to smash and destroy the us semiconductor business and move it overseas…and share hat tech with them and help them use it to sabage people also that the kill American tech people want then to do.. then your sitting around in a semiconductor company unrelated to military industrial complex and they are attacking you there the same way… why are these two connected and joined at the hips? It makes no sense to me… if the foreign agile club wants to sabotage you because you are acseniconducyor designer then way does the military industry complex jobs act like they right arm and do the exact same thing? And on top of it.. you are tagged by bs as described..

  2. Actually I can’t figure out who has them… because I would swear it’s mixed up with the way the Indian service companies studdenly show up around 2008 and started sucking away and hiding all the contractor tech jobs in the US not bolted to the floor…like somehow they stoled military industrial complex “hat” technology and used it to screwup companies into not hiring local Americans in semiconductor field for example..

  3. If I were NSF, I wouldn’t want a single foreigner working on this stuff… it’s too dangerous if miniaturized and delivered covertly… they have to hide this stuff..

  4. the military industrial complex already has bullsh!t like this for espionage purposes… Brain interface implants for spying on high level employees on top secret program, watch foreigners or Americans working overseas.. but mostly it’s used for evil purposes like personal gain…or sabotage attacking people.. controlling companies…. if you are unfortunately enough to have been tagged for working outside of us….they put you in the club to screw you up by sabatoging you by spying on your optic nerve and auditory nerve via brain machine interface… should really be careful who they give research money to for this stuff because its really dangerous and seriously corrupting if misused for spying and espionage… nobody can tell who responsible because it’s a brain interface and nobody believes it’s real… especially if it’s an implant device… also extremely difficult to detect… you can’t really invasively search for a brain machine interface in your brain area without a saw…and nobody wants to do that..
