Sodium titanate (Na_2Ti_3O_7) nanowires were synthesized via a simple hydrothermal method.The properties of the humidity sensor based on sodium titanate nanowires were characterized.Both the response time and the recovery time are short, around 5 s and 6 s, respectively.A great change of the impedance (about five orders of magnitude) was observed at 20 Hz when the relative humidity (RH) varied from 11% to 95%.The curve of impedance vs RH at 20 Hz shows a good linearity.
