Zipangizo zamagetsi zamagetsi zamagetsi zamagetsi zamagetsi zamagetsi zamagetsi zamagetsi zamagetsi zamagetsi ndi mtundu wazidziwitso zogwiritsa ntchito ceramic zomwe zimatha kusintha mphamvu zamagetsi ndi magetsi. Ndi zotsatira za piezoelectric. Kuphatikiza pa piezoelectricity, ma piezoelectric ceramics amakhalanso ndi dielectricity, elasticity, ndi zina zambiri, zomwe zakhala zikugwiritsidwa ntchito kwambiri pakujambula zamankhwala, masensa a Acoustic, ma transducers acoustic, ma ultrasonic motors, ndi zina zambiri.

Zoumba zopangira magetsi zimagwiritsidwa ntchito popanga ma transducers akupanga, ma transducers amadzimadzi, ma transducers amagetsi, zosefera za ceramic, ma ceramic transformer, osankhika a ceramic, ma voliyumu ambiri, ma infrared detectors, zida zamagetsi zowonera, zamagetsi zamagetsi, zoyatsira ndi kuwononga zida, ma piezoelectric gyros, ndi zina zambiri, amagwiritsidwa ntchito osati m'malo okhaokha, komanso m'moyo watsiku ndi tsiku kutumikira anthu ndikupanga moyo wabwino kwa anthu.

Pankhondo yachiwiri yapadziko lonse, zida za BaTiO3 zidapezeka, ndipo zida za piezoelectric ndi momwe amagwiritsira ntchito zidapanga patsogolo. Ndiponano BaTiO3 ufa zimapangitsa kukhala kotheka kupanga BaTiO3 Ceramic yokhala ndi zida zapamwamba kwambiri.

Kumapeto kwa zaka za zana la 20, asayansi azakuthupi ochokera padziko lonse lapansi adayamba kufufuzira zida zamagetsi zatsopano. Kwa nthawi yoyamba, lingaliro la zida za nano lidayambitsidwa pakuphunzira zida zopangira ma piezoelectric, zomwe zidapangitsa kuti kafukufuku ndikupanga zida zopangira ma piezoelectric, zinthu zogwirira ntchito, zikuyenda bwino kwambiri, kuwonekera pazinthu. Kusintha kwa magwiridwe antchito ndikuti makina amagetsi, zida za piezoelectric, ndi ma dielectric asintha kwambiri. Izi mosakayikira zidzakhudza magwiridwe antchito a transducer.

Pakadali pano, njira yayikulu yotengera malingaliro a mita ya nano pazinthu zopangira ma piezoelectric ndikuwongolera zina mwazinthu zopangira ma piezoelectric (onjezerani ma nanoparticles osiyanasiyana kuti apange ma nano complexes mu zida zopangira ma piezoelectric) ndipo (pogwiritsa ntchito ma piezoelectric nanopowders kapena ma Nanocrystals ndi ma polima amapangidwa kukhala zinthu zopangidwa ndi njira zapadera) njira ziwiri. Mwachitsanzo, mu dipatimenti yazinthu zakuthupi ya University of Thanh Ho, kuti akwaniritse kukhathamiritsa ndi kutsalira kwa zotsalira zamagetsi zamagetsi zamagetsi, Ag nanoparticles adawonjezeredwa kuti akonze "nano-multiphase ferroelectric ceramics based on metal nanoparticles / ferroelectric ceramics"; Monga nano alumina (AL2O3) / PZT,nano zirconium dioxide (ZrO2)/ PZT ndi zina za nano zopangira ma cerikeriya amchere kuti achepetse zoyambira zamagetsi k31 ndikuwonjezera kulimba kwa fracture; zida zopangira ma nano piezoelectric ndi ma polima palimodzi kuti apeze zida zama nano piezoelectric. Nthawi ino tiwerenga za kukonzekera kwa ziwiya zadothi zopangira ma piezoelectric pophatikiza ufa wa nano piezoelectric ndi zowonjezera za nano organic, kenako ndikuphunzira kusintha kwa katundu wama piezoelectric ndi ma dielectric.

Tikuyembekezera kugwiritsa ntchito zinthu za nanoparticles muzitsulo zopangira ma piezoelectric!
