Driver’s ECG Signal Detection and Transmission by Impulse-Radio-Based Human Body Communication Technology

Abstract

In this study, we developed a wearable electrocardiogram(ECG) sensor with human body communication (HBC) tech-nology for vital data transmission in a car. The ECG signals were modulated with wideband pulse signals between 10 and 60 MHz based on an impulse radio (IR) scheme, which provides a data rate as high as 1.25 Mbps. To apply the HBC-based wearable ECG in a moving car, we employed a moving average algorithm to reduce the noises produced inthe received ECG signals due to the car's movement. As aresult, we conrmed a real-time ECG transmission of driver in the moving car with a reasonable accuracy.
