To examine the possibility of non-contact unconstrained continuous pulse wave measurement during driving, we installed a microwave Doppler element pulse wave sensor on the dashboard of a large truck. The sensor detects the pulsatile movements of the heart and blood vessels from the Doppler shift of the reflected waves of microwaves emitted toward a person at a distance. We analyzed pulse rate variability from the signal during a long-distance operation and compared it with heart rate variability obtained from ambulatory electrocardiogram recorded simultaneously.
