Abstract
Most of the humidity sensors practically used are based on the change ill e lectrical properties of polymers or ceramics with humidity. They are either resistive-type or capacitive-type sensors. Various chemical modifications of polymeric materials have been utilized to improve the properties of sens ors such as sensitivity, hysteresis, long-term stability, durability in unf avorable atmospheres such as dewdrops or vapors' of volatile organic compou nds(VOC), etc. This paper overviews the novel methods of chemical modificat ion which have been proposed by the authors.
