In the second part, the current-voltage characteristics of the sensors were measured, their charge ionic mobilities were measured with polar inversion method and their ionic numbers were computed. It has found that ionization effect of some binding ions against a critical humidity took place in switchable humidity-sensitive materials, the effect is that some binding ions in materials turn into free ions when a given ambient humidity is reached called a critical humidity, avalanching conduct electricity occurs in materials.
