The SmartShirt System by Sensatex makes it possible to remotely monitor a wearer's movement, heart rate, and respiration rate in real-time through a patented nanotechnology conductive fiber grid that is seamlessly knit into the material of the fully washable shirt.

A company press release describes how it works: The light, breathable, cotton fabric has fully integrated conductive fibers that create connectivity to acquire and transfer analog physiological signals to a small personal controller. The controller digitizes the data signals and wirelessly transmits them to a remote location where the data is received for monitoring.

Possible uses for the system include home health monitoring for the elderly, observing outpatients in post-operative and chronic illness situations, training support for athletes, remote monitoring for first responders, hazard materials workers, and soldiers in the field, and watching professional truck drivers' vital signs to alert them of fatigue.

"Having a reliable way to monitor vital signs in real-time for those with hazardous duty missions would be a tremendous asset," William Earle, former Chief Financial Officer for the Bureau of Alcohol, Tobacco, and Firearms, said.

"There are innumerable ways the Justice Department and the Department of Homeland Security could integrate this system to create and maintain a more secure working environment for their first line responders."

Sensatex is also testing a SmartBra that would employ the same system to remotely monitor vital signs. (photo Sensatex)
