Abstract

A capacitive humidity sensor is used as a test device to characterize the performance of iodine doped polyphenylacetylene(PPA) thin films in relative humidity sensing application In comparison with undoped PPA thin films. the iodine doped PPA films showed higher sensitivity(0.19pF/%RH), better linearity(4.2%FS), much lower hysteresis and lower temperature coefficients(0.043 $\sim$ 0.067pF/$^{\circ}C$) over a wide range of relative humidity.
