The free anion on reduction of the polymer attracts a cation to form a salt in the polymer. An attempt was made to use polypyrrole as a sensing material in measurement of humidity. The gold covered electrode was constructed by employing a photo-resist method and the ionic conductivity of the reduced polypyrrole changes from 2 × 10 kΩ·cm to 3 × 103 kΩ·cm depending on humidity. ？ 1993.
