Piezoelektrik etki, baz\u0131 kristallerin ve seramiklerin mekanik bas\u0131n\u00e7 veya gerilmeye maruz kald\u0131klar\u0131nda elektrik y\u00fck\u00fc \u00fcretme yetene\u011fidir.

Piezoelektrik kelimesi, Yunanca "piezein" kelimesinden gelir ve "s\u0131k\u0131\u015ft\u0131rmak" veya "bas\u0131n\u00e7 uygulamak" anlam\u0131na gelir.

Piezoelektrik Malzemeler<\/h3>\n

Piezoelektrik etkiyi g\u00f6steren bir\u00e7ok malzeme vard\u0131r. Bunlar aras\u0131nda kuvars, turmalin, seramikler (Baryum Titanat, Kur\u015fun Zirkonat Titanat – PZT), ve baz\u0131 polimerler bulunur. PZT, y\u00fcksek piezoelektrik katsay\u0131s\u0131 nedeniyle en yayg\u0131n kullan\u0131lan seramik malzemedir.<\/p>\n\n\n\n\n\n\n\n

Piezoelektrik Etkinin \u00c7al\u0131\u015fma Prensibi<\/h3>\n

Piezoelektrik etki, malzemenin kristal yap\u0131s\u0131ndaki asimetrik y\u00fck da\u011f\u0131l\u0131m\u0131ndan kaynaklan\u0131r. Mekanik bir kuvvet uyguland\u0131\u011f\u0131nda, bu y\u00fck da\u011f\u0131l\u0131m\u0131 bozulur ve malzemenin y\u00fczeyinde bir elektrik y\u00fck\u00fc olu\u015fur. Tersine, bir elektrik alan\u0131 uyguland\u0131\u011f\u0131nda, kristal yap\u0131daki iyonlar yer de\u011fi\u015ftirir ve malzemenin boyutlar\u0131nda bir de\u011fi\u015fiklik meydana gelir.<\/p>\n

Piezoelektrikli\u011fin Uygulamalar\u0131<\/h3>\n

Piezoelektrik etki, \u00e7ok \u00e7e\u015fitli uygulamalarda kullan\u0131l\u0131r. Bunlardan baz\u0131lar\u0131 \u015funlard\u0131r:<\/p>\n
