The humidity-sensitive property of LiCl/H-STI solid electrolyte, which was prepared with assembling a guest of LiCl by a thermal dispersion method on a host of H-form CXN zeolite (STI type), was investigated by the method of AC-impedance. The sample of LiCl/H-STI with threshold loading (0.14g/g) possesses the optimum humidity sensitive performance, including 4 orders of magnitude changes of the electrical conductivity in whole range of the relative humidity, stable sensitivity as well as satisfactory reversibility, exhibiting the desired acute response to the environment moisture. The fact implies that a novel humidity sensor based on this assembly meterial will be very promising in its field.
