Abstract
In a high-aged society, the rate of high-aged drivers is rapidly rising. In accordance with it, traffic accidents by the high-aged drivers are increasing year by year. Main causes of the accidents are said to be functional obstruction of respiration and heartbeat and also the rise of blood pressure.
This paper proposes an unconstrained and noninvasive measurement for respiration and heartbeat for high-aged drivers, which makes use of a wire-type strain gauge installed in (or on) the seat belt of the cars. With the system, not only the average respiration and heartbeat periods but also the instantaneous periods can be measured accurately and efficiently.
