| Abstract: | Sodium titanate (Na2Ti3O7) 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. |
