Scientists at the Pentagon are looking to use a special tattoo to track the vital signs of US soldiers.
The unobtrusive and durable bio-statistic device would monitor a soldier's condition in the field and track their stress levels in an effort to tackle combat fatigue and other problems. DARPA has initiated a request for research proposals designed to provide a solution using advanced materials that can be attached to the skin like a tattoo.
The technology is known as epidermal electronic systems ( EES ), capable of making sensors from lightweight and unobtrusive materials that are flexible and can be stretched without damaging the device. "This innovative design contains all of the necessary components in an ultrathin layer about the thickness of a human hair," said electrical engineer Zhenqiang Ma.
"In its ongoing quest to measure every aspect of US troops’ physiology, the Pentagon’s esoteric research enclave wants to develop a durable, unobtrusive device that can track the body’s physical response to stress."
