RESEARCH & DEVELOPMENT
that does not require surgical implantation but has the precision to
read from and write to 16 independent channels within a 16mm3
volume of neural tissue within 50ms.
Each channel is capable of specifically inter-acting with sub-millimeter
regions of the brain with a spatial and temporal specificity
that is comparable to existing invasive approaches. Individual
devices can be combined to provide the ability to interface to multiple
points in the brain at once. To enable future non-invasive
brain-machine interfaces, N3 researchers are working to develop
solutions that address challenges such as the physics of scattering
and weakening of signals as they pass through skin, skull,
and brain tissue, as well as designing algorithms for decoding and
encoding neural signals that are represented by modalities such
as light, acoustic, or electromagnetic energy.
" If N3 is successful, we'll end up with wearable neural interface
systems that can communicate with the brain from a range of just
a few millimeters, moving neurotechnology beyond the clinic and
into practical use for national security, " Emondi said. " Just as service
members put on protective and tactical gear in preparation for
a mission, in the future they might put on a headset containing a
neural interface, use the technology however it's needed, then put
the tool aside when the mission is complete. "

of developing a high-performance, bi-directional brain-computer
interface (BCI) for clinical applications or for use by able-bodied
members of the military. "
" Our work centers around magnetoelectric nanotransducers
(MEnTs) localized in neural tissue for subsequent bi-directional
neural interfacing. Our preliminary research gives us a high degree
of confidence in programmatic success and we would be remiss
if we did not give credit to our incredible team that includes
Cellular Nanomed Inc., the University of Miami, Indiana University-Purdue
University Indianapolis, Carnegie Mellon University, the
University of Pittsburgh and the Air Force Research Laboratory. "

Arafura Resources is striving to be the next strategic global supplier
of neodymium and praseodymium (NdPr) rare earth minerals from
Australia for the manufacture of NdFeB permanent magnets to
support the global e-mobility and electrification revolution.
A single magnetoelectric nanotransducer
For the BrainSTORMS project, the Battelle team, under principal
investigator Dr. Patrick Ganzer, 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.
" At Battelle, we're excited about the BrainSTORMS (Brain System
to Transmit Or Receive Magnetoelectric Signals) program, " commented
Ganzer. " We are continuing to work on the second phase
