Designed by a team of American scientists, the new men's briefs come with an electronic biosenser that can measure blood pressure, heart rate and other vital signs - all printed on the waistband.

They are supposedly comfy, durable, stylish and be able to save the wearer's life.

"We envision all the trend of personalised medicine for remote monitoring of the elderly at home, monitoring a wide range of biomedical markers, like cardiac markers, alerting for any potential stroke, diabetic changes and other changes related to other biomedical scenario," professor Joseph Wang of University of California San Diego,a nano-engineering expert who developed the technology, tells Reuters.

He adds that wearable biosensors can also provide valuable information to athletes, identify type of injury or even measure blood alcohol levels.

Since the project is being funded by the US military, it is most likely that the American troops will be the first batch to try out the high-tech underwear.
