Capacitive humidity sensors were made of nanometer barium *** pellets were prepared under different pressures between 3920N to 7850N *** capacitance changes in three orders of magnitude in the relative humidity range of 10%～98%,indicating high humidity sensitivity of the *** a certain measuring frequency,the capacitance of the sensors increases as increasing of the preparation pressure,while the sensitivity of the sensors basically remains the *** frequencies corresponding to the peaks of the dielectric loss of the sensors move to the higher frequency direction as increasing of the relative *** a certain humidity,the frequencies corresponding to the peaks of the dielectric loss move to the higher frequency direction as increasing of the preparation pressure.
