Electrospum polyaniline nanofibers doped with palladium nanoparticles have been demonstrated for hydrogen sensing in the formation of a chemresistor. These nanofibers have been deposited as single nanofibers across two gold electrodes by means of near-field electrospinning without using the conventional lithography process. These palladium nanoparticle based chemresistors have recorded 1.8% resistance change in the environment with 0.3% hydrogen concentration. These nanofibers sensors are flexible with good reversibility and potentially versatile by doping with different particles. As such, nanofiber-based sensors could be promising for environmental and industrial applications.
