This research focuses on the incorporation of pH-sensitive nanoparticles into electrospun fibers to function as a sweat monitoring device. In order to determine how fiber size
effects the relationship between nanoparticle dye intensity and pH value, the fibers were electrospun at three different speeds: 0.03 mL/hr, 0.3 mL/hr and 0.3 mL/min. These speeds produced fibers
of approximately 1.3 μm, 1.8 μm, and 9.5 μm in diameter, respectively. The research found that nanoparticles with smaller fibers are more sensitive to pH change than larger fibers.
