Technically known as a “wear and forget physiological sensing system,” thinking undergarments may be the next-generation drawers for the modern warfighter.

Gel-free sensors form an electronic network in the fabric to monitor respiration and heart rate, activity, body posture and skin temperature -- relaying that data through the warfighters’ layers of clothing to a central system. The technology could provide an unprecedented capability not just to monitor warfighters during combat and identify critical casualties but also to train and select for missions.
