Abstract

The topic of the article is the design and construction of the device for measurement of ECG in the car. This device is divided into two parts: sensing part and processing part. These parts are described in detail in separated sections. The sensing part of the device was incorporated into the driver's seat. The ECG signal is measured through capacitive coupled electrodes installed in the seat that includes high-input impedance amplifier and sensing electrode surface. This sensing part of the device is capable of recording electrocardiogram data through clothing. Part of the hardware responsible for processing of the recorded signal was placed out of the seat and it is connected through shielded cable with sensing electrodes in order to reduce noise. The main part of the hardware dealing with signal digitalization and filtration utilizes analog front-end ADS1191 by Texas Instrument. It is possible to set up sampling frequency, gain of channel and configuration of RLD circuit during data acquisition. The experimental measurement and ability of the device to measure capacitive coupled ECG while driving are presented at the end of the article.
