Determining the pH of a chronic wound is one of the key indicators for the treatment progress. Since pH sensor made of polymer films possess limited flexibility and breathability, the sensors may cause discomfort to the patients who lie on beds for a long time. A pH sensor that can be continuous monitoring over large areas with enhanced flexibility and breathability is required. In this study, we propose a highly flexible textile pH sensor using polyaniline as a working electrode to solve this problem. Polyaniline(PANI) can have different level of conductivity depending on the concentration of hydrogen ions in its environment, which can generate electromotive force to a reference electrode. During the fabrication of a working electrode, carbon nanotubes and agarose were added to polyaniline suspension to improve conductivity and durability. We confirmed the performance of the fabricated pH sensor by measuring the potential difference as a function of the pH of sample buffer solutions.
