Piezoelectric ceramics o se ituaiga o faʻamatalaga mea faʻaoga keramika e mafai ona faʻaliliuina le malosi faʻainisinia ma le eletise eletise i le tasi ma le isi.O se aafiaga piezoelectric.I le faaopoopo atu i le piezoelectricity, piezoelectric ceramics o loʻo i ai foi le dielectricity, elasticity, ma isi mea, lea na faʻaaogaina lautele i ata faʻafomaʻi, masini faʻalogo, transducers acoustic, masini ultrasonic, ma isi.

Piezoelectric ceramics e masani ona faʻaaogaina i le gaosiga o le ultrasonic transducers, underwater acoustic transducers, electroacoustic transducers, keramika faamama, sima transformers, sima faʻailoga, eletise eletise maualuga, infrared detectors, luga o le acoustic waves masini, electro-optic Devices, faʻamumu ma faʻavevesi masini, piezoelectric gyros, ma isi, e faʻaaogaina e le gata i fanua tekonolosi maualuga, ae faʻapea foʻi i le olaga i aso uma e tautua ai tagata ma fatuina se olaga sili atu mo tagata.

I le Taua Lona Lua a le Lalolagi, na maua ai sima BaTiO3, ma mea piezoelectric ma a latou talosaga na alualu i luma le taimi.Manano BaTiO3 pautaia mafai ona gaosia le BaTiO3 Ceramic ma mea e sili atu ona maualuga.

I le faaiuga o le 20th seneturi, na amata suʻesuʻe e saienitisi mea mai le salafa o le lalolagi mea fou ferroelectric.Mo le taimi muamua, o le manatu o mea nano na faʻaofiina i le suʻesuʻeina o mea piezoelectric, lea na faia ai le suʻesuʻega ma le atinaʻeina o mea piezoelectric, o se mea aoga, e feagai ma se faʻalavelave tele, faʻaalia i meafaitino.O le suiga i le faʻatinoga o mea faʻainisinia, mea piezoelectric, ma meatotino dielectric ua matua faʻaleleia.E mautinoa lava o le a iai se aafiaga lelei i le faatinoga o le transducer.

I le taimi nei, o le auala autu o le faʻaaogaina o le nano mita manatu i mea piezoelectric aoga o le faʻaleleia lea o nisi meatotino o mea piezoelectric (faʻaopoopo nanoparticles eseese e fausia ai nano complexes i mea piezoelectric) ma (faʻaaogaina piezoelectric nanopowders poʻo Nanocrystals ma polymers e faia i mea tuʻufaʻatasia e auala faapitoa) 2 auala.Mo se faʻataʻitaʻiga, i le matagaluega o meafaitino a le Iunivesite o Thanh Ho, ina ia faʻaleleia atili le saturation polarization ma le toega o le polarization o mea ferroelectric ceramic, na faʻaopoopoina Ag nanoparticles e saunia ai "nano-multiphase ferroelectric ceramics e faʻavae i luga ole nanoparticles / ferroelectric ceramics";E pei ole nano alumina (AL2O3) /PZT,nano zirconium dioxide (ZrO2)/PZT ma isi mea fa'apipi'i nano fa'apipi'i ferroelectric e fa'aitiitia ai le mea muamua ferroelectric k31 ma fa'ateleina ai le gau gau;o mea piezoelectric nano ma polymers faʻatasi e maua ai mea faʻapipiʻi nano piezoelectric.O le taimi lenei o le a tatou suʻesuʻeina le sauniuniga o le piezoelectric ceramics e ala i le tuʻufaʻatasia o nano piezoelectric powders ma nano organic additives, ona suʻesuʻeina lea o suiga i mea piezoelectric ma meatotino dielectric.

Matou te faʻamoemoeina le tele ma le tele o faʻaoga o mea nanoparticles i le piezoelectric ceramics!
