T/RH-sensitive thick-film structures for ecological control and environment monitoring

T/RH-sensitive thick-film structures based on spinel-type semiconducting and dielectric ceramics of different chemical composition Cu_0.1Ni_0.1Co_1.6Mn_1.2O₄ (with p⁺-type of electrical conductivity), Cu_0.1Ni_0.8Co_0.2Mn_1.9O₄ (with p-type of electrical conductivity) and magnesium aluminate MgAl₂O₄ ceramics were fabricated and studied. These elements are shown to be successfully applied for integrated T/RH-sensitive sensor structures of environmental monitoring and control.
