Abstract
(Na0.5Bi0.5)0.94TiO3–Ba0.06TiO3 (NBT–BT6) nanofibers were synthesized by electrospinning and characterized by X-ray diffraction, field emission scanning electron microscopy, and transmission electron microscopy. The humidity sensor was fabricated by coating NBT–BT6 nanofiber on a ceramic substrate with Ag–Pd interdigitated electrodes. At 100 Hz, the impedance of the humidity sensor changed by more than five orders of magnitude with the relative humidity (RH) changing from 11% to 95%. The response time and recovery time were about 2 s and 50 s, respectively, and the maximum hysteresis was around 5% RH. The results indicate that NBT–BT6 nanofibers are of great potential for high-performance humidity sensor applications.
