| Abstract: | The humidity response caused by conductivity and dissipation,which occur in the real and imaginary parts of a dielectric constant in titania ceramics,was investigated using lockin amplifier.The effect of surface treatment on the humidity response was also considered.The calculated results from a simple model of a watermoleculefilmsensorsystem given by the paper are in good agreement with all the experimental results.The paper indicates that water vapor molecules adsorbed on the sensor surface play a very important role in the humidity response process. |
