Abstract Scope Nanofibers have superior surface-to-volume ratios compared to vapor deposited thin films. High surface-to-volume ratio and short diffusion paths in the cross-section of the nanofibers are expected to improve the sensitivity response time, and recovery time to gas exposures when integrated into a sensor. Electrospinning is an efficient and scalable manufacturing technology for the production of a wide variety of nanofiber materials, including several materials with potential applications for sensors. A ceramic precursor solution suitable for electrospinning was established and consists of polyvinylpyrrolidone and gallium nitrate. Calcining of the fibers remove polyvinylpyrrolidone and converts the nitrate into gallium oxide. Initial experiments explore the effect of both nitrate concentration in the precursor solution and the collector distance on both the shrinkage of the nanofiber mat and the fiber diameters. The next phase of experimentation is full integration of the fibers with electrode arrays for use in oxygen sensor testing at high temperatures.
