Abstract

Wearable devices have emerged as a promising solution in the medical field, offering early diagnosis and effective monitoring. E-textile is a type of biosensor that can potentially be used in wearable devices for pH monitoring purposes. The purpose of this research paper is to compare the effectiveness of two different pH sensing materials: reduced graphene oxide-polyaniline (rGO-PANI) modified screen electrode and Ruthenium (IV) Oxide (RuO2) coated thread for creating e-textiles. The study evaluated the sensitivity of both sensing materials for pH detection and found that both are suitable for this purpose. However, the results show that the rGO-PANI-modified electrode is more sensitive (with a sensitivity of -54.2 mV/pH) compared to the RuO2-coated thread (with a sensitivity of -47.7 mV/pH). The findings of this study suggest that e-textile biosensors have great potential in the medical field and that their sensitivity can be further improved through material modification and optimization.
