Abstract :
This paper proposes an unconstrained and noninvasive measurement system of heartbeat and respiration for drivers. The system makes use of a wire-type strain gauge set on a seat belt and measures instantaneous heartbeat and respiration periods efficiently based on their dynamic models and maximum likelihood method.
