Multi-objective optimization of the parameters of TiO_2-based ceramic humidity sensors

摘要

An investigation of ceramic humidity sensing elements based on titanium dioxide with dopants of PbO, Bi_2O_3 and Na_2CO_3 ? 10H_2O has been performed. To study the complex influence of dopants and sintering temperature on the parameters and characteristics of the ceramic humidity sensors, an experimental design has been performed. A multi-objective optimization based on the method of general loss functions was carried out. The optimal composition of dopants and sintering temperature were determined to obtain ceramic sensors with optimal parameters. Experimental samples based on this optimal composition and temperature were prepared and investigated.
