    Tomoki-san,

    The HDC3020 structure is like option B, where the electrode does not contact air directly, but uses a polymer as an intermediate medium. The polymer captures water vapor, which will alter the relative permittivity of the polymer, triggering a change in capacitance between the electrodes that is translated into a %RH value.

    Regards
