A group of scientists and researchers at the Fraunhofer Institute for Photonic Microsystems have developed an innovative electrocardiogram device that is capable of operating from a car's driver's seat. The device is essentially designed to monitor the heart rate of the driver and prevent any accidents that may occur due to incapacitation or heart failure.
It turns out that driver incapacitaton due to heart attacks and other cardiovascular problems is one of the leading causes of car accidents. The seat is designed to prevent such accidents, and can be used in conjunction with automated vehicle emergency response technologies such as emergency stop assistance gadgets and active braking mechanisms. The electrocardiogram itself works without direct contact with the driver's body.
This device is a marvel because it is designed to save drivers' lives without intruding on their driving experience in any way.
