Noninvasive sensors to detect human physiological parameters are becoming more and more important. This is especially useful to monitor driver state as driver-vehicle system is a safety-critical system. Unfortunately, current technologies in these noninvasive sensors development are not satisfactory. In this research, we developed an intelligent integrated device called "smart wheel" to monitor drivers' physiology. Specifically, a group of polyvinylidene fluoride (PVDF) sensor, semiconductor temperature sensor, and piezoresistive sensor were integrated into a driving steering wheel. The developed device has the capability of measuring a driver's pulse wave, breathing wave, skin temperature, and gripping force in a noninvasive manner and in real time. A pilot experiment was carried out to verify the pulse wave measurement of this intelligent sensor and the result was found satisfactory
