Inside The Pentagon’s Wearable Tech Revolution
“Poor Bob,” says Alexander Gruentzig, pointing at a model with a screwdriver deal with protruding of its proper shoulder. The founding father of the Boston-area startup Legionarius stabbed Bob to reveal the talents of a camouflage uniform shirt it’s carrying that incorporates a light-weight sensor layer developed by his firm. The “sensible shirt” has despatched an alert to a tactical smartphone that exhibits the realm of the wound, Bob’s important indicators and site. The intention, says Gruentzig, is to get assist to wounded troopers sooner.
Legionarius’ sensible shirt is designed to detect tears made by high-velocity impacts like gunshots or shrapnel and ship alerts to a medic’s smartphone.

“Ninety p.c of preventable fight deaths are attributable to huge hemorrhaging. When you can cease the bleeding within the first minute the prospect of survival goes up tremendously,” Greuntzig advised Forbes earlier this month at a protection commerce present in Washington, D.C., the place his expertise was featured as one of many winners of the Military’s newest XTechSearch contest.
The sensible uniform, which Legionarius has been creating with the assistance of U.S. Particular Operations Command and roughly $1.1 million in authorities funding, is a part of a wave of labor throughout the U.S. army to develop wearable expertise to guard troopers and higher gauge their bodily situation in actual time. It ranges from efforts to harness client sensible watches and different health units that monitor exertion to cutting-edge analysis to control the mind to enhance sleep and to develop an Iron Man-like helmet that might detect threats and activate countermeasures to guard in opposition to concussion and directed vitality weapons.
“The army has traditionally been like, if I need to make you a greater soldier, I’ll provide you with a greater gun,” says Brandon Marcello, a sports activities physiologist who’s labored with professional groups on bettering efficiency. He’s at present concerned with a U.S. Military Futures Command program known as Optimizing the Human Weapon System (OHWS) that’s utilizing health-tracking wearables with troopers. Its purpose: “How can we now optimize the human and make them smarter, extra deadly, extra exact?” he says.
The coronavirus pandemic served as an accelerant. In 2020, the Protection Innovation Unit distributed 1000’s of Garmin sensible wristwatches and Oura finger rings to trace service members’ temperature, pulse and blood oxygen ranges and located that it may predict Covid-19 instances with 73% accuracy. It was an enlargement of a DIU initiative begun in 2018 with Philips Healthcare known as Fast Evaluation of Menace Publicity (RATE) that developed an algorithm aimed toward predicting a variety of widespread diseases 48 hours earlier than signs are displayed.
With Optimizing the Human Weapon System, Military brass additionally wished to see if client wearables may very well be used to diagnose Covid, however this system is rather more than simply tip-offs for sickness. For the previous two years, OHWS has used the Oura ring to evaluate high quality of sleep and Polar Grit X Professional sensible watches to observe coronary heart price and exertion amongst a battalion of 530 troopers from the tenth Mountain Division at Fort Drum, New York, and whereas deployed at a base in Afghanistan. The info has additionally been utilized by a associated effort known as Measuring and Advancing Soldier Tactical Readiness and Effectiveness, or MASTR-E, to develop algorithms to foretell troopers’ efficiency.
On a unit degree, MASTR-E, OHWS and related Navy and Air Drive packages intention to assist commanders know when their troops are being pushed an excessive amount of or will be skilled tougher, and for the person soldier, give them suggestions on issues like how their respiration results their marksmanship, or how a heavy evening’s consuming impacts their efficiency the following day.
OHWS, which can be expanded subsequent yr to a small brigade of two,000, is making an attempt to show troopers “the why behind their physiology in order that they really make higher decisions on the particular person degree,” says program supervisor Joseph Patterson.
The info additionally encourages officers to have interaction extra with their troopers and “turn into extra caring,” says Patterson, “extra human.”
If a soldier has elevated respiration and in a single day coronary heart charges, it may very well be an indicator of stress that ideas off officers to test in, says Marcello. “It may very well be something from, ‘Let’s get them examined for Covid,’ to, ‘Hey, this appears to be like like a psychological well being challenge. Let’s intervene earlier than something actually unhealthy occurs.’ ”
LifeLens has spent six years creating its sensor, which it says can be utilized for all kinds of well being monitoring, from important indicators to detecting gait abnormalities and early indicators of an infection.

Shopper health trackers make sense throughout coaching, however they could not have the battery life to final throughout a mission, and plenty of can’t hyperlink up with tactical communication techniques, says Alan Harner of the U.S. Military Medical Materiel Growth Exercise. He’s product supervisor for a cross-services program that’s creating a tiny bio-sensor with the Pennsylvania-based startup LifeLens Applied sciences that’s tailor-made for area deployment and that they are saying can monitor 150 forms of well being information, from important indicators to underhydration to blast pressures that might result in mind accidents.
The system is an adhesive patch containing a seven-layer stretchable circuit with a nickel-sized disc within the heart that has a processor, transmitter and battery with 72 hours’ energy. It’s positioned on the chest, which offers extra correct readings on important indicators than wrist- or finger-worn client units, and it’s snug sufficient that customers can neglect it’s there, says LifeLens CEO Landy Toth.
Dubbed the Well being Readiness And Efficiency System (HRAPS), it’s been trialed to stop warmth accidents in coaching by Military Rangers at Fort Benning, Georgia, and with U.S. Particular Forces. It’s on monitor to be the primary wearable to transition to wider distribution by way of the Military’s Program Government Workplace Soldier, which accelerates growth of kit, Harner says.
For all of the promise of wearables, Marcello says they could simply be a transition expertise to much less noticeable types of well being monitoring like diagnostic tattoos and “nearables,” which might test important indicators visually from afar.

The army can be backing “moonshot” packages, like a $2.8 million Military-funded effort centered at Houston’s Rice College to develop a cap that might enhance troopers’ sleep by stimulating the circulation of the glymphatic system within the mind, which is believed to wash out metabolic waste.
It’s formidable, partially, as a result of it’s not settled science but that the glymphatic system, which has been documented in animals, exists in people, says Paul Cherukuri, a former biomedical system developer answerable for the venture who’s Rice’s vp for innovation.
The marching orders from the Military program supervisor: “I would like you guys to go for a Nobel in addition to a model new wearable,” Cherukuri says.
A prototype of a sensible helmet designed by Rice College researchers, that includes a matrix produced on a Carbon 3D printer that they are saying will incorporate sensors and different techniques to actively defend the wearer.

Cherukuri can be main a $1.3 million Navy-backed venture primarily based at Rice to construct a futuristic helmet that he likens to Iron Man’s, popularized within the Marvel motion pictures starring Robert Downey Jr., full with a rudimentary model of his AI assistant JARVIS that might detect threats and deploy lively protections.
Engineers on the venture are working with the California 3D-printing unicorn Carbon to develop new light-weight polymers to extrude a lattice-like framework for the helmet that may be custom-printed to suit particular person troopers.
They plan to include tiny lensless flat cameras developed at Rice and different sensors. The helmet would interpret sensor information to warn troopers of risks exterior their field of regard, both through haptics or a heads up show, and take countermeasures. Cherukuri hopes to make use of strategies he’s helped develop to manipulate nanomaterials with electrical fields to counter blast forces and stop traumatic mind accidents, in addition to to erect an electromagnetic defend in opposition to directed vitality weapons like these suspected to be behind Havana Syndrome.
They’ve mocked up a Mark 1 model that’s double the goal weight of three kilos. Cherukuri says among the many laborious elements at this level are constructing the smarts to interpret sensor info and determining how one can equip the helmet with sufficient energy.
The intention, he says, is to assist “the fellows who’re going to be within the gap for a really, very very long time who’re disconnected from residence base. Can we preserve them alive and wholesome?”
A priority for all wearable packages—past proving their expertise really works—is discovering the funding to maintain them wholesome by way of the DoD’s dreaded “Valley of Loss of life,” when analysis grants run out and there’s no instant acquisitions choice that might get it to the holy land of army tasks: turning into a so-called “program of document,” with its personal line within the finances. HRAPS has completed that. RATE, the hassle to make use of wearables to foretell sickness, has not. Its former program supervisor has argued its destiny is a case examine in how innovation will be stymied by the Pentagon’s slow-moving forms.
Harner says it’s vital for the Pentagon to work with corporations which have civil clients to supply different sources of income.
HRAPS associate LifeLens, which gained clearance for its system final yr from the Meals and Drug Administration, has additionally been advertising it to hospitals.
Legionarius founder Gruentzig is making an attempt to promote first responders on his sensible shirt. He says a number of state police SWAT groups are fascinated by testing it. Gruentzig and his three teammates have labored on including air bladders to the shirt that might inflate round a wound to supply compression to cease bleeding, however they’re not searching for to commercialize it till a possible buyer exhibits curiosity.
For now, he’s wanting ahead to getting again on a base to do extra testing with the Military after the pandemic made that tough. “Getting these items soiled,” Gruentzig says, pointing to hangers displaying his sensible shirts, “that’s what we’re searching for.”
