ʻO ka Piezoelectric ceramics kahi ʻano o ka ʻike hana ceramic mea hiki ke hoʻololi i ka ikehu mechanical a me ka ikehu uila i kekahi i kekahi.He hopena piezoelectric.Ma waho aʻe o ka piezoelectricity, piezoelectric ceramics pū kekahi dielectricity, elasticity, etc., i hoʻohana nui ʻia i ka lāʻau lapaʻau, Acoustic sensors, acoustic transducers, ultrasonic motors, etc.
Hoʻohana nui ʻia ka Piezoelectric ceramics i ka hana ʻana i nā transducers ultrasonic, underwater acoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers, ceramic discriminators, high voltage generators, infrared detectors, surface acoustic wave device, electro-optic Devices, igniting and detonating devices, ʻO nā piezoelectric gyros, a me nā mea'ē aʻe,ʻaʻole i hoʻohana waleʻia ma nāʻenehana kiʻekiʻe, akā, i ka nohona o kēlā me kēia lā e lawelawe i nā kānaka a no ka hanaʻana i kahi ola maikaʻi no nā kānaka.
I ke Kaua Honua II, ua ʻike ʻia nā seramika BaTiO3, a ua holomua nā mea piezoelectric a me kā lākou mau noi.Anano BaTiO3 paukae hiki ai ke hana i ka BaTiO3 Ceramic me nā waiwai ʻoi aku ka holomua.
I ka hopena o ke kenekulia 20, ua hoʻomaka nā ʻepekema waiwai mai nā wahi a puni e ʻimi i nā mea ferroelectric hou.No ka manawa mua, ua hoʻokomo ʻia ka manaʻo o nā mea nano i ke aʻo ʻana i nā mea piezoelectric, ka mea i hana i ka noiʻi a me ka hoʻomohala ʻana i nā mea piezoelectric, kahi mea hana, ke alo i kahi holomua nui, i hōʻike ʻia i nā mea.ʻO ka hoʻololi ʻana i ka hana ʻo ia ka mea i hoʻomaikaʻi maikaʻi ʻia nā waiwai mechanical, piezoelectric, a me nā waiwai dielectric.He hopena maikaʻi kēia i ka hana o ka transducer.
I kēia manawa, ʻo ke ala nui o ka hoʻohana ʻana i ka manaʻo nano mika i nā mea piezoelectric hana e hoʻomaikaʻi i kekahi mau waiwai o nā mea piezoelectric (hoʻohui i nā nanoparticles ʻē aʻe e hana i nā paʻakikī nano i nā mea piezoelectric) a (e hoʻohana ana i nā nanopowders piezoelectric a i ʻole Nanocrystals a me nā polymers i hana ʻia i nā mea composite e. mea kūikawā) 2 mau ʻano.No ka laʻana, i loko o ke keʻena waiwai o Thanh Ho University, i mea e hoʻomaikaʻi i ka saturation polarization a me ke koena polarization o ferroelectric ceramic mea, Ag nanoparticles ua hoʻohui 'ia e hoomakaukau "nano-multiphase ferroelectric ceramics ma muli o metala nanoparticles / ferroelectric ceramics";E like me nano alumina (AL2O3) /PZT,nano zirconium dioxide (ZrO2)/PZT a me nā mea ʻē aʻe nano composite ferroelectric ceramics e hōʻemi i ka mea ferroelectric kumu k31 a hoʻonui i ka paʻakikī o ka haki;nā mea nano piezoelectric a me nā polymers e loaʻa ai ka nano piezoelectric composite material.I kēia manawa e aʻo mākou i ka hoʻomākaukau ʻana i nā ceramics piezoelectric ma ka hoʻohui ʻana i nā pauka nano piezoelectric me nā mea hoʻohui nano organik, a laila e aʻo i nā loli i nā waiwai piezoelectric a me nā waiwai dielectric.
Ke manaʻolana nei mākou i nā noi hou aʻe o nā mea nanoparticles i nā ceramics piezoelectric!
