Sol-gel spin coated titanium dioxide (TiO2) was applied as the sensing membrane for extended gate field effect transistor (EGFET) pH sensor. The molarity of the TiO2 sol-gel was manipulated to study its influence on the film pH sensing capability. In this study, the sol-gel solution concentration wa...
