Flexible electrodes made of cotton fabric with silver nanoparticles (AgNP) and polyaniline (PANI) were fabricated to capture muscle biopotential signals using electromyography (EMG). Changes in the pH of the AgNP solution during the synthesis process greatly influence the electrode’s performance. By analyzing the physicochemical characteristics of AgNP, measuring the electrical conductivity of each sample, and contrasting flexible electrode performance during EMG measurements, the impact of varying AgNP pH solutions will be investigated. According to the study, utilizing AgNP synthesized in the alkaline solution combined with PANI produces fabric-based flexible electrodes with a higher signal-to-noise ratio (SNR) and better conductivity than the standard Ag/AgCl commercial electrodes. Additionally, the alkaline solution-produced AgNP had a smaller particle size and greater crystallinity. During EMG monitoring, the absence of an electrolyte gel in the fabricated flexible electrode can provide comfort to the user without any risk of skin irritation from an electrolyte gel. The AgNP-PANI fabric electrode synthesized with AgNP in an alkaline solution has superior properties that make it potentially become a decent future commercial electrode for biopotential measurement.
