Explanation

ceramics materials whose electrical parameters change with the physical and chemical parameters of the environment. According to the physical and chemical parameters of the induction environment, it can be divided into physical sensitivity, chemical sensitivity, and biological sensitivity. Physical sensitive ceramics mainly include: photosensitive, such as CdS, CdSe, etc; Thermal sensitive, such as PTCR ceramics, NTC, CTR thermosensitive ceramics; Magnetic sensitivity, such as InSb, InAs, GaAs, etc; Sound sensitivity, such as rosite, crystal, BaTi03, PZT, etc; Pressure sensitive, such as ZnO, SiC, etc; Li Min, such as PbTiO3, PZT, etc. Chemical sensitive ceramics mainly include: gas sensing, such as SnO2, ZnO, ZrO2, etc; Humidity sensitive, such as TiO2 MgCr2O4, etc. Biological sensitive ceramics are still under development.
