More Information
Summary:The present invention relates to a piezoelectric ceramic composition for sensors. The piezoelectric ceramic composition for sensors capable of simplifying signal processing algorithm with excellent signal resolving power by improving sensitivity with clear differentiation between a noise and a transceiving signal and having an excellent electric property since at least one additive selected from a group formed of La2O3, Nd2O3, and Sm2O3 is included in PbNb2O6 (Lead metaniobate) or additive such as Sr2O3 is included in PbNb2O6.
