The measured signals were verified by commercial devices to confirm data correctness and accuracy. The developed steering wheel was tested under laboratory and real-life conditions. In addition, an inertial unit was integrated into the steering wheel to record and analyze the movement patterns performed by the driver while driving.
The crucial parameters in health or drowsiness monitoring, such as heart rate, heart rate variability, and blood oxygenation, are measured by an electrocardiograph and oximeter integrated into the steering wheel. The purpose was to create a unique, comprehensive monitoring system for the driver. The aging population, cardiovascular disease, personalized medicine, and driver fatigue were significant motivations for developing a monitoring platform in cars because people spent much time in cars. This article describes the design of a smart steering wheel intended for use in unobtrusive health and drowsiness monitoring.
