abstract = "The sensing elements for humidity has been vastly researched to be
applied in several areas, since automotive and food industries up
to automation in the agricultural production and in the
environmental monitoring. In this work, ceramic material are
focused, owing to their unique structure, consisting of grains,
grain boundaries, surfaces and pores, the control of which allow
to obtain suitable microstructure to be used as humidity sensors.
In this work, the influence of the relative humidity on the
electrical conductivity of the ceramic sensing elements of ZrO2
and of TiO2, under specific climatic conditions, is investigated.
In this sense, the ceramics used as humidity sensing elements were
manufactured through conventional ceramic processing. The sintered
ceramics were characterized through X-ray diffractometry
techniques, scanning electron microscopy, apparent density by the
Archimedes principle and linear retraction. The results showed the
development of a solid solution of ZrO2-TiO2. The microstructures
presented a homogeneous distribution of pores. The ceramic
tablets, sintered at 1100 °C, evidenced a linear behaviour in the
curves capacitance versus environment humidity. © (2014) Trans
