Development and application of piezoceramics

Piezoelektrični efekt otkrili su braća Jacques i Pierre Curie. To je pojava električnog potencijala, odnosno napona na stranama kristala kada je podvrgnut mehaničkom naprezanju. Razlikujemo direktni i inverzni piezoelektrični efekt. Piezoelektrične keramike spadaju u skupinu oksidnih keramika te pripadaju anorganskim piezoelektričnim materijalima. Posjeduju nesređenu pervoskitnu kristalnu strukturu. Piezoelektrični keramički materijali imaju široku primjenu te se koriste kao senzori, generatori, aktuatori i pretvarači. Barijev titanat, olovni cirkonat titanat, stroncijev titanat te litijev niobat su najčešće korišteni piezoelektrični keramički materijali. Novim trendovima na širokom rasponu područja pokušava se poboljšati razvoj piezolektričnih keramičkih materijala.The piezoelectric effect was discovered by brothers Jacques and Pierre Curie. It is the appearance o fan electric potential that is a voltage on the sides of the crystal when it is subjected to mechanical stress. We differentiate direct and inverse piezoelectric effect. Piezoelectric ceramics belong to the group of oxide ceramics and belong to inorganic piezoelectric materials. They possess a disordered primordial crystal structure. Piezoelectric ceramic materials have a wide range of applications and are used as sensors, generators, actuators and transducers. Barium titanate, lead zirconate titanate, strontium titanate and lithium niobate are the most commonly used piezoelectric ceramic materials. New trend sin a wide range of areas are trying to improve the development of piezoelectric ceramic materials
