Driving Health Home
Two commercially available sensors are key elements of the integrated vital signs measurement system. One of them shines infrared light into the fingers and measures the heart rate and oxygen saturation via reflected light; the second measures the electric conductance of the skin upon contact.
The scientists have also developed a micro-controller application that processes the data and transfers them back to the vehicle. In order to extend the data pool and make as many reliable assertions as possible on the state of a driver’s health, a radio connection can be established to additional external devices, e.g. a blood pressure monitor. A driver’s skin conductance, for instance, reveals whether he or she is under severe stress, or whether his or her blood pressure exceeds a critical value.
