In one of the more odd products to be unveiled at CES, Philips Electronics plans to launch eUnderpants, suggests Engadget.

The garment will monitor the wearer's hearth rhythm, blood pressure and is even said to be able to detect a loss of consciousness. The clothing item can even call emergency services and inform aid workers about the exact location of the patient through a GPS device.

SV Sleuth has send an email to the product development team at Philips, suggesting that the company adds a peer to peer tracking service that allows spouses to monitor where the underwear goes and to scrutinise what other e-knickers come in its vicinity

We were however unable to answer the most important question: what colours will the garment come in?
