Innovation Research contracts and by an earlier Army program called Technolo- gies for Metabolic Monitoring. Te Army is also leveraging the National Science Foundation’s Center
Powered Systems of Integrated Sensors and Technologies program that is develop- ing the next-generation, ultra-low-power RT-PSM “system on a chip.”
Wearable physiological monitoring tech- nologies are essential tools needed to understand Soldier physiology in train- ing and operational field environments.
WHY IS THIS TECHNOLOGY AVAILABLE NOW? for Advanced Self-
It wasn’t a bolt out of the blue—rather, it was the result of years of field and lab research coupled with a few breakthroughs.
Previous efforts to analyze temperature data couldn’t distinguish between peak performance and imminent heat injury. But when an equation was developed to predict core temperature rise based on heart-rate monitoring over time—the kind of data that these chest-worn sensors provide—real-time physiological monitoring became a tool of practical use. Mathematical models that combine workload and thermal strain more reliably warn of approaching performance limits based on individual cardiovascular responses.
Other applications hold promise, too: real-time neuropsychological status for alert- ness, wearable biomechanical performance assessments that signal optimal per- formance and impending musculoskeletal injury, and better thermal-strain monitor- ing for military working dogs.
Knowledge
gained will
lead to new
insights into individual and small-unit leader readiness and help guide changes in field doctrine, materiel development targets and strategies, and trade-space analyses. Physiological models can embody knowledge gained from field and lab studies, and enable predictions for conditions not yet experienced. Tis capability goes beyond simply dupli- cating the roles of good leadership and training; it is an important part of what makes real-time monitoring useful.
PACE YOURSELF People directed to walk or run five miles in one hour without overheating or excess fatigue performed better when given pacing guidance derived from real-time monitoring of their physi- ological signs. This finding could help the Army plan routes, taking into account optimal pace and workload for each team member. (Photo by Dr. Mark Buller, USARIEM)
Working Soldiers until failure is costly—there are the long-term costs of musculoskeletal injury and health management, lost expertise and time and expense of training replacements. RT-PSM systems can identify markers of compromised performance or safety, enabling early intervention when a known need exists.
