Textronic clothing to ECG measurement

Continuous measurement of physiological parameters enable to monitoring healthy and ill state of patients or people who are exposed to health hazard what is the result of their professions. Rescuers (firefighters, chemical rescuers etc.), solders, policemen and people practicing of competitive sport include of this category. Measurement of chosen vital signs is possible using textronic clothing that includes sensors and measurement setups integrated with clothing structures. Sensors implemented in clothing ensures noninvasive measurement method, without interfering into human body. In this paper authors presented the textronic system to ECG measurement. This system consists of two parts: textile and electronic modules. Textile module composed of shirt with integrated textile measurement ECG electrodes connected with electronic measurement system. Measurement electrodes have a composite, textile structure and they were made from electroconductive textile materials. To construction used silver woven fabric. The woven fabric was prepared by Soliani SML company from Italy. Measurement system for ECG monitoring used three electrodes. These electrodes were connected to low offset voltage, very precise instrumentation amplifier. Signal from amplifier were filtered by computer software. The ECG signal was analyzed after filtering. During research properties of textiles ECG electrodes was compared with traditional ECG medical electrodes.
