Abstract
To develop a wearable multi-lead electrocardiogram (ECG) measuring system, we fabricated the electrodes and wires by using electrostatic flocking technology on a textile. By using this technology, it was possible to fabricate many electrodes and wires, simultaneously. Also the flocked electrodes and wires had stretchability and washing resistance properties. To use dry electrodes, it is important to reduce the influence of motion artifacts (MAs). The results of the experiment with the skin phantom revealed that the contact pressure between the skin and the electrode is an important factor in MA reduction. Then, we conducted experiments with a human body to determine the relationship between the contact pressure and the MAs. Under the pressures of 200 Pa and 500 Pa, MAs were observed. Meanwhile, under the pressures of 1000 Pa, 2000Pa and 4000 Pa, the ECG signals under rest and deep breathing conditions were able to be measured without MAs. Considering the comfortability, the contact pressure from 1000 Pa to 2000 is preferable. Finally, we fabricated the wearable ECG measuring system and succeeded in measuring 18-lead ECG signals. The measured ECG waveform is in good agreement with the ECG waveform measured by a commercial system.
Highlights
When measuring a 12-lead ECG signal, it is necessary to attach at least ten electrodes
After printing the adhesive paste on the textile, Ag-plated fiber was formed by electrostatic flocking technology, which charges the fiber and sprays it along the electric field that aligns the charge fibers vertically
The skin phantom used in the experiment had mechanical characteristics, which were identical to the characteristics of the human skin
Summary
When measuring a 12-lead ECG signal, it is necessary to attach at least ten electrodes (four electrodes on the limb, and six electrodes around the chest). We developed a wearable multi-lead ECG measuring system, which was fabricated by using electrostatic flocking technology. Rai et al had reported the development of a dry electrode and a patch electrode by the electrostatic flocking technology[18,19]. They succeed in measuring ECG signals with the flocked electrode. We can focus on reducing the MAs caused by breathing From these experimental results, we determined the contact pressure required between the skin and the flocked electrodes to measure the ECG signals without MAs. we fabricated the wearable multi-lead ECG measuring system and measured the 12-ECG signals
