Sensors stop drivers from dozing off

摘要

A German engineering company has developed sensor technology that prevents drivers from falling asleep while behind the wheel. Sensofoil, from Hoffmann + Krippner, consists of sensors within the steering wheel that can detect minute changes in the pressure and positioning of the driver's hands. In response to such changes, an alert such as a seat vibration or sound is triggered to restore concentration or prompt the driver to pull over and rest. Traffic experts claim that 25% of all road accidents are caused by extreme fatigue. Hoffmann + Krippner said the technology could react to a change in pressure within 200 milliseconds, quick enough to prevent drivers from taking 'micro-sleeps', a leading cause of accidents.
