Summary:
The brain activity when a person is awake is completely different to that in a state of drowsiness. "One of the easiest methods of finding brain activity is to do an electroencephalogram or EEG. Instead, sensors are placed inside the car seat's fabric. It may not work inside a car," said professor Venkatesh Balasubramanian, department of engineering design, IIT-M, who led the research. Unlike the regular ECGs in doctors' clinics, these machines do not have electrodes that are stuck to the skin..
