Abstract
Some health complexity happens during driving like heart problem, stroke etc. Driver’s health abnormality may also effect safety of other vehicles. So in recent years, automotive manufacturers and users are interested to implement real-time health monitoring in car system. In cardiac monitoring systems, a sensor is an important element. It is not only the type of sensor that determines the correct operation of a system, but also the processing of the registered signals. This paper analyses the influence of the sensor pressing force on the estimation of the stiffness of the artery to describe the pulse signal processing.
