Introduction
What Piezoelectric Ceramics?
Piezoelectric ceramics known what called piezoelectric reverse piezoelectric effects. piezoelectric effect causes crystal produce electrical potential when subjected mechanical vibration. contrast, reverse piezoelectric effect causes crystal produce vibration when placed electric field. piezoelectric materials, Rochelle salt quartz have long been known single-crystal piezoelectric substances. However, these substances have relatively limited application range chiefly because poor crystal stability Rochelle salt limited degree freedom characteristics quartz. Later, barium titanate(BaTiO3), piezoelectric ceramic, introduced applications ultrasonic transducers, mainly fish finders. More recently, lead titanate, lead zirconate system(PbTiO3PbZrO3) appeared, which electromechanical transformation efficiency stability(including temperature characteristics)far superior existing substances. dramatically broadened application range piezoelectric ceramics. When compared which other piezoelectric substances, both BaTiO3 PbTiO3PbZrO3 have following advantages: Advantages qHigh electromechanical transformation efficiency. wHigh machinability. broad range characteristics achieved with different material compositions (high degree freedom characteristics design). rHigh stability. tSuitable mass production, economical. Murata, forerunner piezoelectric ceramic industry, offers extensive range products with piezoelectric applications.
Properties Piezoelectric Ceramics
Piezoelectric ceramics type multi-crystal dielectric with high dielectric constant formed processes first, high temperature firing. After firing, they have characteristic crystal structure shown Fig. exhibit piezoelectric property because electrical dipoles within crystals oriented random overall moment dipoles canceled out. make ceramics piezoelectric they must polarized. electric field several kV/mm applied piece ceramic align internal electrical dipoles single orientation (see Fig. (b)). strong dielectric property ceramic, dipole moment remains unchanged after electric field removed, ceramic thus exhibits strong piezoelectric property (see Fig. (c)). When signal applied piezoelectric ceramic (piezoelectric transducer) frequency matching specific elastic frequency ceramics (which depends shape material), ceramic exhibits resonance. Since ceramic very high electromechanical transforming efficiency point resonance, many applications this resonance point. Also piezoelectric ceramics when molded certain shapes have more than point resonance depending vibration mode. such case, vibration mode most suited application selected.

Every object surface electrical charges charges given from other objects. These electrical charges cause object have certain electric potential with respect other objects. electric potential sensor designed measure this surface potential. There major surface potential detection methods field-mill method vibrating capacitance method. former method synchronously shuts electrical flux from object surface modulates electric field incident sensing electrode induce current electrode, proportional surface potential (DC). latter method forms capacitance across surface object sensing electrode, vibrates sensing electrode vertically surface object induce electrical charges which proportional capacitance surface potential, thereby obtaining current proportional surface potential (DC). Murata's potential sensors, high-precision, piezoelectric tuning fork ("MICROFORK") with proven production record, achieve field shut-off vibration electrode vibration. Integrating signal processing circuit, Murata's electric potential sensor assures high operating stability reliability.
