We have developed a built-in vital sign sensor, which allows drivers to noninvasively measure their heartbeat and pulse wave just by gripping the steering wheel in the usual manner. Unlike conventional vital sign sensors used in clinical practice, such as an electrocardiogram sensor for measuring the heartbeat and photoplethysmogram sensor for measuring the pulse wave, our system requires no preparation or gel. One of the major issues we have successfully addressed is the suppression of mechanical vibration and electrical noise affecting the pulse wave sensor, which is far more susceptible to disturbances than heartbeat monitoring, especially while driving.
