The aim of this study was to evaluate a conductive/capacitive hybrid electrocardiogram (ECG) measurement method for monitoring the drowsiness of a driver during car driving. A triple-layer capacitive-coupling electrode comprising driven-shield and sensing electrodes was introduced to reduce the ambient noise, such as the electrostatic induction noise caused by buttock friction. An experiment modeling a car interior showed that the triple-layer electrode successfully reduced the baseline fluctuation and stably measured the ECG R-peaks. The result shows the feasibility of stable R–R interval detection during driving using the conductive/capacitive hybrid ECG measurement system.
