　　开车打瞌睡?智能安全带叫醒你

　　The Daily Mail: A seatbelt that wakes you up if you are in danger of falling asleep at the wheel is being developed by scientists.

　　The device measures the driver's heart rate and breathing via a sensor¹ system knitted into the seatbelt and seat cover. If the rates drop too much, a warning alarm goes off.

　　The designers say the system is innovative² because it can cancel out the motion of the car and only pick up heart and respiratory rate thanks to the 'smart textile materials' embedded³ in the seat cover and seatbelt.

　　These materials are composed of a combination of fibres and yarns⁴ with electrical properties which are mixed with the standard material of the seat and belt. The team say it is a 'state of the art unobtrusive testing' and the testing device will be 'invisible to the user'.
