This is an interesting idea, a pair of pants that keep a check on the wearers blood pressure. The pants called "smart pants" contain sensors in the waistband that pick up information on how fast blood is flowing through the arteries, this can give vital clues about the condition of the artery walls and act as an early warning system to pick up any problems. They are still in the experimental stage but Phillips has recently applied for a patent for the idea so they might well be in the shops soon.
