From John Keller's 3-26-18 Military & Aerospace Electronics article entitled "DARPA Eyes New Neural Interfaces to Connect Warfighters Hands-free to Advanced Military Systems":
U.S. military researchers are asking for industry's help in developing non-invasive or minimally invasive neural interfaces to connect warfighters directly to computers or other digital devices to enable fast, effective, and intuitive hands-free interaction with military systems.
Officials of the U.S. Defense Advanced Research Projects Agency
(DARPA) in Arlington, Va., issued a presolicitation Friday
(HR001118S0029) for the Next-Generation Non-Surgical Neurotechnology
(N3) project to develop a nonsurgical neural interface system to broaden
the applicability of neural interfaces to the able-bodied warfighter.
Until now, neural interfaces that connect human brains to computers
and other digital equipment have been surgically invasive and used
primarily to help restore functions and skills to injured warfighters.
The N3 project, however, seeks to enable neural recording and
stimulation with sub-millimeter spatial resolution in healthy
Neural interfaces could enable warfighters to multitask more
efficiently, and interact with autonomous and semi-autonomous systems --
particularly future systems equipped with artificial intelligence (AI),
The problem with human-machine neural interfaces today is how
surgically invasive they are. State-of-the-art high-resolution
single-neuron or neural-ensemble neural interfaces are invasive, and
require surgical implantation of metal or silicon-based electrodes into
brain tissue or on the surface of the brain [...].
Non invasive interfaces will involve sensors and stimulators that do
not breach the skin. Minutely invasive approaches, meanwhile, will
permit nonsurgical delivery of a nanotransducer delivered to neurons of
Transducers should be small enough so as not to cause tissue damage
or impede the natural neuronal circuit, and will be external to the
skull. Non invasive and minutely invasive approaches will be necessary
to overcome issues with signal scattering, attenuation, and
signal-to-noise ratio [...].
The N3 program will provide as long as four years of funding to
deliver a nonsurgical neural interface system and is divided into three
sequential phases: a one-year base effort, and two 18-month option
Proposers must use approaches that ensure confidentiality, integrity,
and availability (also known as the CIA triad) to prevent spoofing,
tampering, or denial of service. It will be necessary to secure
connections among the integrated device, the processing unit, and the
system user’s brain.
